Ethane Lewis Dot Structure would refer to the structure formation of the compound ethane with chemical description. Detailed structure by explaining the facts shown by Lewis structure would be represented in this research.
The factors that would be covered in this article are being listed below:
Valance electrons of Ethane
One ethane molecule consists of two carbon and six oxygen atoms. The chemical formula of the molecule is C2H6. The total number of valance electrons in this compound is 14.
It is very important to understand the calculation of valance electron ion making the Lewis dot structure if the molecules. The valance electrons are the main participants in formation of the binds between the different atoms.
In the case of calculating the number of valance electrons of the each atom it is in- s needed to identify the number of valance electrons hold by the atoms. Therefore, let us find the total number of electrons in each of the carbon and hydrogen atoms.
The total number of electrons in carbon is six and total number of election in one hydrogen atom is one. In the first electronic shell of carbon, there are two electrons and the second shell, that is the highest energy level of the atom possesses four electron which does not satisfies octet. Therefore, the number of valance electrons in carbon is four.
Besides, as one hydrogen atom hold only one single electron in its only electronic shell, the valance of hydrogen atom is one. Therefore, it is clear that in the formation of Lewis dot structure four valance elections from each of the two Carbon atoms and one valance electron from each of the six-hydrogen atom take place.
The total number of valance electrons that is found in the C2H6 is 4*(2) + 6*(1) = 14.
The sharing of these valance electrons takes place to create bonds between the atoms. It has been identified that the bonds in this organic molecule is single covalent bonds. This sharing happens due to the urge of the atoms in filling the octet, which is provides extern=me stability to the atoms like noble gases.
Ethane Lewis dot structure drawing
The steps of generating Lewis dot structure of this organic compound would be drawn in this section. The drawing would be relevant to discuss the systematic formation of the structure of C2H6. The participation of the valance electrons would describe the procedure and crate a valuable knowledge regarding the chemistry behind the existence of C2H6.
In the case if preparing the Lewis dot structure of the molecules it is need to understand the participation criterion of the valance electrons in the bonding procedure happens between the atoms.
Let us draw the Lewis dot structure of Ethane, C2H6:
The above picture is the representation of the position of valance electrons in C2H6. This is the basic Lewis dot structure of the molecule. The dots are the symbol of valance electrons.
There are two carbon atom participates in this sharing. Each one of them shares one electron with each other and creates on single bond. Other three valance electrons of the Carbon atoms are shared with three Hydrogen atoms.
One carbon shares three electrons with three hydrogen atoms and other one shares its three valance electrons with another three hydrogen atoms. This is how they make single bonds and crates C2H6 by using all the valance electrons.
Hydrogen atoms also share their electrons with the carbon atoms. Therefore, Mutual electron sharing happens and proofs that the compound is a covalent compound.
In this way, the atoms fill their octet. All the atoms including carbon and hydrogen get stability like their nearest noble gas. As Helium is the nearest noble gas of hydrogen and holds two electrons in its structure hydrogen aims to get the same electronic configuration like helium. Neon is the nearest one for Carbon and therefore; carbon aims to get the electronic configuration of Neon.
This urge of having same electronic configuration of Helium and Neon for hydrogen and Carbon respectively drives them towards this electron sharing reaction. It makes them to be bound with each other with covalent bind.
Facts represented by Lewis dot structure of Ethane
There are few facts about the compound is shared by the Lewis dot structure. Those facts are about the internal shape of molecule and the detail information about the formation of the molecule.
Lewis dot structure of ethane helps to identify the electronic arrangement inside the molecule. This arrangement and the surge of having a specific number of electrons in the configuration by the elements of ethane are notified by the Lewis dot structure.
According to VSEPR theory, ethane possesses tetrahedral geometry. This theory refers to the concept of valance shell electron pair repulsion inside the molecules. It emphasises the electronic structure and geometry of the compounds by finding the strength of repulsion of the bonding pair electrons and the lone pairs.
Ethane does not have any lone pair. That is a sp3 hybridised tetrahedral molecule. This VSEPR theory is explained by the Lewis dot structure of the Ethane. The molecular structure of Ethane says that it is a covalent compound and it follows the octet rule.
The equal electron distribution among each of the electrons according to their needs is represented by this dot structure. The electron share and the theory behind it is explained and justified by the Lewis dot structure.
Frequently Asked Questions (FAQs)
Question 1: What is the main remark represented by VSEPR theory?
Answer: VSEPR (Valance Shell Electron Pair Repulsion) theory shows the participations of valance electrons in making bonds between the elements. This theory represents the repulsion characteristics shown the by the bonding, non-bonding electrons and lone pair electrons in a molecule. It emphasises the concept of making a stable molecular geometry of a compound.
Question 2: Why does Ethane considered as a covalent compound?
Answer: In the case of formation of Ethane the electrons are shared by the elements. Both Carbon and Hydrogen share their electrons with each other. No element transfers its electrons to others. Therefore, it is considered as a covalent compound.
Question 3: How do Hydrogen atoms fill their octet in C2H6?
Answer: Carbon has four valance electrons therefore, it needs four more to fill octet bad Hydrogen has 1 valance electron so it needs one more electron to get the same configuration like Helium.
The both of the Carbon with each other share one valance electron from four and other three are shared with Hydrogen molecules. In addition, hydrogen molecules share their only electron with them as well.
Question 4: What is the difference between the molecular structure of Ethane and Ethene?
Answer: In the molecular structure of ethane, atoms are found six hydrogen as participants. Both the carbon atoms shares only one electron with each other and creates a single bond between them.
In the molecular structure of Ethene, there is four hydrogen atoms are found to be the participants. The carbon atoms share two of their election with each other and create double bond between them.
Question 5: What is the total number of valance electron present in Ethene?
Answer: In Ethene there are four hydrogen molecules participate shared by hydrogen atoms is 4*1 = 4 and the total number of valance electron shared by carbon atoms is 2*4 = 8. Therefore, the total number of valance electrons present in Ethene is (8=4) = 12.
Question 6: Write the difference between structural formula of Ethane, Ethene.
Answer: As the number of participated hydrogen atoms is six in Ethane the chemical formula of Ethane is C2H6. The number of participated hydrogen atoms is four in Ethene, therefore; the chemical formula of Ethene is C2H4. However, the basic difference between their structural formula is the different number of hydrogen atoms in the compounds.
