Dichloromethane or methylene chloride (commonly known as DCM) is volatile and commonly used as a solvent. Let us explore some facts about Dichloromethane in this article in brief.
Dichloromethane is prepared by the reaction of Chloromethane(CH3Cl) with Chlorine which results in the production of chloromethane, Dichloromethane, hydrogen chloride which is a by product and chloroform gas at a temperature of 400–500 °C. Later on, The method that is used for their separation is Distillation.
It has a great capability to dissolve a large number of organic compounds hence making it a very useful solvent. Further in the article, we will discuss the physiochemical properties, such as boiling point and oxidation state of Dichloromethane.
Dichloromethane IUPAC name
The IUPAC name of CCl2H2 is Dichloromethane.
Dichloromethane Chemical Formula
The chemical formula of Dichloromethane is CCl2H2.
Dichloromethane CAS number
The CAS number (authentic numeric identifier which can contain up to 10 digits) of Dichloromethane is 75-09-2.
Dichloromethane ChemSpider ID
The ChemSpider ID (Chemspider is a free chemical structure database ) for Dichloromethane is 6104.
Dichloromethane Chemical Classification
Dichloromethane is chemically classified as an organochlorine compound.
Dichloromethane molar mass
The molar mass (mass of one mole of a substance) of Dichloromethane is 84.93 g/mol.
Dichloromethane color
Dichloromethane appears as a colourless liquid.
Dichloromethane viscosity
The viscosity of Dichloromethane is 0.437 mPa.
Dichloromethane molar density
The molar Density of Dichloromethane is 1.3266 g/cm3.
Dichloromethane melting point
The melting point of Dichloromethane is -96.7 °C or -142.06°F. This implies that it has very low intermolecular forces.
Dichloromethane boiling point
The boiling point of Dichloromethane is 39.6 °C or 103.3°F. The reason Dichloromethane has a low boiling point is that it is a non-flammable solvent.
Dichloromethane state at room temperature
At room temperature, Dichloromethane is a liquid. It is not miscible in water, but It is dissolvable in most of the organic solvents such as ethanol, ether, phenols, aldehydes and ketones.
Dichloromethane covalent radius
Dichloromethane does not have a covalent radius as it is non-reactive in nature.
Dichloromethane covalent bond
Dichloromethane shows covalent bonding as the centre atom Carbon is hybridized, having hybridization sp3, and the molecule forms all four bonds in a compound.
Dichloromethane electron configurations
Electronic Configurations show how the distribution of electrons in the orbitals takes place. Let us further discuss this in bit detail as we can not predict the electronic configuration of a complex.
- The electronic configuration of Carbon is written as [He]2s22p2.
- For Hydrogen electronic configuration is 1s1.
- The electronic configuration of Chlorine is [Ne]3s23p5.
Dichloromethane oxidation state
The oxidation state of Dichloromethane is 0, because the oxidation state of hydrogen is always +1, and for halogens, that is, Chlorine is -1.
Dichloromethane acidity
Dichloromethane is a lewis acid and Dichloromethane accepts electrons very easily, thus making it a lewis acid.
Is Dichloromethane odourless
Dichloromethane has a sweet chloroform-like odour.
Is Dichloromethane paramagnetic
A compound is said to be paramagnetic when its electrons are not completely paired. Let us find if Dichloromethane is paramagnetic or not.
Dichloromethane is diamagnetic in nature as all electrons are completely paired.
Dichloromethane hydrates
Dichloromethane is moderately soluble in water.
Dichloromethane crystal structure
In its crystal form, Dichloromethane has a tetrahedral structure.
Dichloromethane polarity and conductivity
- Dichloromethane is polar in nature because of its geometry which is tetrahedral, and also, individual bond dipoles do not cancel each other. Another significant explanation behind this is the distinction in electronegativities of carbon, chlorine and hydrogen atoms.
- The thermal conductivity of Dichloromethane is 0.1392 W/m/K
Dichloromethane reaction with acid
Dichloromethane does not react with any acid. In fact, it is highly unreactive in nature.
Dichloromethane reaction with base
Dichloromethane does not react with bases because of its inert nature. Dichloromethane, along with pyridine derivatives, is used in reactions because of the fact that Dichloromethane is very versatile as a solvent.
Dichloromethane reaction with oxide
No reaction takes place because it is highly stable.
Dichloromethane reaction with metal
Dichloromethane does not react with metals because of its inert nature.
Conclusion
Dichloromethane is a non-flammable liquid which has wide use as a solvent because of its versatile nature as a solvent. Food technology and pharmaceutical companies are the major fields where Dichloromethane is used, hence making it very useful. It has a tetrahedral geometry and is polar in nature.
