Methylene chloride, additionally known as Dichloromethane (DCM), is an organic chemical compound. CH2Cl2 is the chemical formula because that DCM. The is a colorless and volatile liquid v a sweet smell. The compound is naturally obtained from the volcanoes, wetlands and also other oceanic sources. It has plenty of uses, but majorly it is used in the food industry. In this article, us will know the structure, molecular geometry, applications and also other chemistry properties in detail.

CH2Cl2 Lewis structure

For knowledge the properties and structure of any chemical compounds, including organic ones, that lewis framework is the the utmost importance. Lewis framework is a theory that help in expertise the structure of a offered compound, based on the octet rule. According to the octet rule, a molecule should have actually eight electrons in its outer shell to come to be inert or stable. For this compound, over there is one molecule the Carbon, 2 molecules that Hydrogen and also two molecules of Chlorine.

To know the lewis structure, that is vital to uncover the number of valence electrons in the compound. Valence electrons are the sum full of the electrons every molecule has actually in their outer shell in a compound. This electrons encompass the persons that take part in link formation and also the ones the don’t get involved in forming bonds. The electrons the are involved in bond development are dubbed bonding pairs of electrons. Conversely, the people that carry out not participate in forming any bonds are dubbed lone bag of electron or non-bonding pairs of electrons.

In Lewis structure the lines stand for the bonds and dots represent the valence electrons. Once we talk around CH2Cl2, Carbon is less electronegative 보다 Chlorine atoms. To recognize the Lewis structure lets an initial calculate the total number of valence electrons for Dichloromethane.

Carbon has four valence electrons, Hydrogen has one valence electrons and like every halogens, Chlorine has actually seven valence electrons.

Total number of Valence electron = 4 + 2*1 + 2*7

= 4+2+14

= 20

There space twenty valence electron in the compound, and also four bonds room formed. Central carbon atom creates two bonds with both Hydrogen and also Chlorine atoms. Thus 4 valence electrons of Carbon, two electrons of Hydrogen and also Chlorine each participate in the link formation. 

Hybridization that Dichloromethane


When two or molecules take part in the link formation, your orbitals overlap as result of the share of electrons. These overlapped orbitals are referred to as hybrid orbitals. The bonds developed in Dichloromethane space covalent bonds. Main Carbon is hybridized together the molecule forms all the 4 bonds in the compound. An electron indigenous the 22 orbital and also three other electrons from 2p orbitals get involved in forming bonds. Thus the hybridization the Carbon atom in CH2Cl2 is sp3.

Molecular Geometry the Dichloromethane

It is comparatively basic to know the molecular geometry the a compound after learning its Lewis structure and also hybridization. The arrangement of the molecule in this compound is such the the Carbon atom is in the main atom, one Hydrogen atom is on the top topmost position and also the various other one is top top the left next of the central atom. Similarly, one chlorine atom is to the best of Carbon and the various other one is one the downward position of the main atom. Together the hybridization is sp3, the molecular geometry the Dichloromethane becomes tetrahedral. The form of the compound is a trigonal pyramidal. 

Polarity that Dichloromethane


The polarity of any kind of compound relies on the lone bag of electrons and also symmetry the the compound. It likewise depends top top the electronegativity the the molecule participating in the development of the compound. Right here Hydrogen atom is less electronegative 보다 chlorine atom and also hence, over there is a network dipole moment in the compound. Also, the setup of the bonded bag is asymmetric, which makes Dichloromethane polar.

Physical Properties

Now the we understand all around the chemical properties and also structures of CH2Cl2 let’s have actually a look at its physical properties.

Property that the compoundExperimental values
Density the DCM1.3226 g/cm3
Molecular load of DCM84.93 g/mol
Boiling point of DCM39.60C
Melting suggest of DCM-97.60C

Uses the Dichloromethane

DCM is offered as a solvent in the food industry and as a repaint remover.It is also used as a degreasing agent.The link is also used in the production of aerosol formulations.

Hazards of making use of Dichloromethane

As the link is extremely volatile in nature, it can cause acute inhalation hazards. Lengthy exposure to DCM can reason dizziness, fatigue, headache and much more as a result of acute absorb of the gas.It has additionally been connected to various species of cancer and thus is a carcinogenic compound.The compound is additionally not safe for people with heart-related problems as the can cause abnormal heart rhythms and heart assaults when inhaled for prolonged period.In some cases, it can additionally irritate the nose and also throat.

Concluding Remarks

I expect this post gives you comprehensive information about Dichloromethane. The compound has actually twenty valence electrons, the end of i beg your pardon eight electrons take part in shortcut formation. It has sp3 hybridization and polar. DCM has tetrahedral molecular geometry and it is trigonal pyramidal in shape.
