Representation of valence electrons of any molecule in the form of schematic structure having line and dots are known as Lewis structure. Let us take a look on it below.
NO2F lewis structure composed of mainly three elements i.e. one nitrogen, two oxygen and one fluorine atoms. NO2F is known as Nitryl fluoride. All the three elements in this lewis structure are non – metals. Nitrogen takes the central position in the structure due to its high electronegativity.
In NO2F lewis structure, 2 oxygen atoms and 1 fluorine atoms bonded to central nitrogen atom with three strong sigma covalent bond. Remaining valence electrons are placed on outer 2 O atoms and 1 F atom which are shown as dots. Let us discuss in brief about the NO2F lewis structure, its characteristics and some important facts about it.
How to draw NO2F lewis structure?
To draw lewis structure we have to follow some steps and rules. Let us have a look on steps to draw lewis structure given below.
Count Valence electrons and selection of central atom:
Sum the valence electrons of nitrogen, oxygen and fluorine atoms to know the total valence electrons of NO2F lewis structure. Then select the central atom which has low electronegativity. Therefore, nitrogen atom takes the central position in NO2F lewis structure.
Mark lone pair electrons and apply octet rule:
Make three single bonds within all N, O and F atoms of NO2F lewis structure. Extra valence electrons should be placed on outer one fluorine and two oxygen atoms and count them. Apply octet rule on all atoms and check whether the atoms has complete or incomplete octets.
Calculate formal charge and predict the shape.
Evaluate the formal charge of all N, O and F atoms in NO2F lewis structure with the help of given formula. Then with the help of VSEPR theory, predict the shape, hybridization and bond angle of NO2F lewis structure.
NO2F valence electrons
The atom of any element contains electrons in its outermost shell of atomic orbital is known as valence electrons. Below is the description on NO2F valance electrons.
NO2F lewis structure contains total 24 valence electrons present on it. Nitrogen contains 5 valence electrons as it comes under 15th group. Oxygen contains 6 valence electrons as it belongs to 16th group. Fluorine has 7 valence electrons as it represented to the 17th periodic table group.
Step by step calculation for NO2F lewis structure valence electrons is explained below.
- Sum of valence electrons of N, O2 and F atoms = ( 5 N + (6 x 2) O + 7 F ) = 24
- Total valence electrons on NO2F lewis structure is = 24
- To calculate electron pairs on NO2F lewis structure, divide its valence electrons by 2 = 24 / 2 = 12
- Therefore, total electron pairs on NO2F = 12
- Hence, the NO2F lewis structure contains 24 valence electrons and 12 electron pairs.
NO2F lewis structure lone pairs
Extra non – bonding electrons which get unshared in the structure are known to be lone pair electrons. Here, some description on NO2F lone pair electrons given below.
NO2F lewis structure contains 9 total lone pair electrons. It composed of 24 valence electrons. From them 6 valence electrons can act as bond pair electron due to covalent bond formation with N, O and F atoms. Extra 18 remained non – bonding (valence) electrons go to outer O and F atoms.
Each O atom can take more 6 non – bonding electron and F atom can also take more 6 non – bonding electrons. Hence, each F and O atoms has 6 non – bonding electrons which get paired into 3 lone pair electrons. So, each F and O atoms has 3 lone pair electrons. Therefore, NO2F lewis structure has 9 lone pair electrons.
NO2F lewis structure octet rule
Octet rule tells that the atom with eight electrons in its outer valence shell is the stable atom. Let us have some brief discussion on NO2F lewis structure octet rule.
In NO2F lewis structure, outer 2 O and 1 F atom has complete octets but central N atom has incomplete octet. The central N atoms contains 6 bonding electron due to three single covalent bonds with 2 O and 1 F atoms. Hence, the central N atom has incomplete octet with only 6 electrons.
The outer three atoms i.e. 1 F and 2 O atoms contain total 8 electrons. Each outer atom has 2 bonding electrons and 6 non – bonding electrons. Therefore, the outer O and F atoms has 2 ( B.E. ) + 6 ( N.B.E ) = 8 electrons and thus have complete octets.
NO2F lewis structure formal charge
The minimum positive / negative charge creates on atom due to loss or gain of electrons is known as formal charge. The calculative part of NO2F formal charge given below.
Formal charge of NO2F lewis structure is = (valence electrons – non-bonding electrons – ½ bonding electrons)
Above is the formula to calculate formal charge which is used to calculate NO2F lewis structure formal charge in below given table.
| Atoms of NO2F lewis structure | Valence electrons on N, O and F | Non – bonding electrons on N, O and F | Bonding electrons on N, O and F | Formal charge on N, O and F |
| Nitrogen atom (N) | 05 | 00 | 06 | ( 5 – 0 – 6 / 2 ) = + 2 |
| Oxygen atom (O) | 06 | 06 | 02 | ( 6 – 6 – 2 / 2 ) = – 1 |
| Fluorine atom (F) | 07 | 06 | 02 | ( 7 – 6 – 2 / 2 ) = 0 |
NO2F lewis structure resonance
A same compound with various forms having same atomic position but different bonding is known as resonance structure. Let us discuss NO2F resonance structure.
NO2F lewis structure shows 2 resonating structures. NO2F resonance structures are formed due to movement of electron on both O atoms. 1 lone pair electron on O atom get moved inside to form double bond within N and O atoms (N=O) and the charge on N atom get minimize to form stable structure.
Below is the explanation for two NO2F resonance structures.
- NO2 Resonance structure 1= One lone pair electron get moved from right side oxygen atom to form double bond. Formal charge get minimize on N from + 2 to + 1 and on right O from – 1 to 0.
- NO2 Resonance structure 2 = One lone pair electron get moved from left side oxygen atom to form double bond. Formal charge get minimize on N from + 2 to + 1 on left O from – 1 to 0.
NO2F lewis structure shape
The compounds having arrangement of atoms formed in a particular manner as per their valency and bonding forming a shape. Let us discuss about NO2F shape.
NO2F lewis structure contains trigonal planar shape and geometry. As per the VSEPR theory module of molecular structures, NO2F molecule comes under AX3 generic formula. Here A is central atom and X3 is three bonded atoms to A. There is no lone pair electron on central N atom.
According to VSEPR module the NO2F compound has no lone pair electrons and the central N atom bonded to 3 outer atoms i.e. 2 oxygen atoms placed laterally on either side of N atom. While the F atom placed at top side of N atom.
NO2F lewis structure angle
Angle formed within the two immediate bonds within the structure is the bond angle of that structure. Below is the explanation on NO2F bond angle.
NO2F lewis structure has 1200 bond angle. The central N atom linked with two O atoms on its either sides forming O – N – O bond angle. The F atom placed at top position linked with central N atom forming F – N – O bond angle.
NO2F hybridization
The formation of new hybrid orbital of same energy by mixing and recasting the atomic orbital is known as hybridization. Look the description on NO2F hybridization below.
NO2F lewis structure has sp2 hybridization. The steric number of nitrogen atom is (bonded atoms N + lone pair electron on N) i.e. 3 + 0 = 3. The calculated value of central nitrogen atom steric number is 3. So it has mixing of 3 atomic orbitals of nitrogen atom.
One ‘s’ and two ‘p’ orbitals of nitrogen atoms get mixed and recast to form a new hybrid sp2 hybrid orbital of equivalent energy.
Is NO2F soluble in water?
The high capacity of solute to dissolve into a solvent is known as solubility. Here we are discussing on the NO2F solubility in water.
NO2F is soluble in water. On adding NO2F in water hydrolysis reaction occurs within the solution. Thus, when NO2F reacts with water there is the production of two acids. It gets dissociates in water as NO2+ and F- ions. Hence, it shows its soluble nature towards H2O.
How NO2F is soluble in water?
NO2F is water soluble in nature. As if we add a quantity of NO2F in H2O, it undergoes hydrolysis reaction and the negative ion (F-) part of NO2F gets attracted to positive ionic (H+) part of water. Likewise positive ion (NO2+) of NO2F goes attracted towards negative (OH-) ionic part of water.
The reaction of NO2F and H2O producing acids is denotes as NO2F + H2O → HNO3 + HF.

NO2F compound is molecular in nature. It has three covalent bonds within all its N, O and F atoms. They are connected to each other by forming two N – O covalent bonds and one N – F covalent bonds. Thus it forms a molecule and being molecular in nature.
Its formula shows the molecular number of oxygen that indicates the presence of two oxygen molecules in the NO2F molecule. Thus, NO2F shows the characteristics of being molecular by having covalent bonds and molecular number in its formula NO2F is molecular compound.
Is NO2F an acid or base?
Species which are proton or H+ ion donor is acid and the species which are proton or H+ acceptor. Take a look on topic is NO2F acid or base.
NO2F is not an acid or a base. As it can behave as a NO2F is a strong oxidising agent. The compounds containing nitrates are consider as oxidizers. Therefore, NO2F containing nitrate molecule is an oxidizing agent.
Is NO2F an electrolyte?
The compounds which get ionised when mixed with water and capable to conduct electricity are known as electrolytes. Let us know about NO2F electrolytic nature.
NO2F is not an electrolyte. Because it is not an ionic compound and cannot form ions. NO2F is a molecular compound containing 3 covalent bonds in its structure. On adding NO2F in water it cannot completely dissociates into ions to conduct electricity.
Is NO2F a salt?
