methylene chloride

Methylene Choride

Methylene Chloride is a polyatomic molecule which consists of two chlorine atoms attached by single bonds to a methyl group.


	DZV model of Methylene Chloride.

The DZV model of Methylene Chloride is the optimal model for showing the geometry of Methylene Chloride.

Bond Lengths

Atoms	621-G	631-G	DZV
C to H	0.107 nm	0.107 nm	0.107 nm
C to Cl	0.185 nm	0.183 nm	0.183 nm


	Model of the HUMO orbitals of DZV Methylene Chloride.

The HOMO orbitals are the highest highest energy molecular orbitals occupied by electrons. For methylene chloride the orbitals are non-bonding, this will help show how the molecule will react.


	Model of the DZV LUMO orbitals for Methylene Chloride.

The LUMO orbitals are the lowest energy molecular orbitals occupied by electrons. For Methylene Chloride the LUMO orbitals are bonding, which will help determine how the molecule will react.


	Model of electrostatic potential for methylene chloride.

The electrostatic potential for methylene chloride is as expected, there is a large electron cloud around the chlorides. It is expected that there would be such a large electron cloud around the chloride because chlorides have such a large number of valence electrons.

Dipole Moment
The calculated dipole moment for methylene chloride was found to be 2.529460 debye. The experimental value for the dipole moment of methylene chloride was found to be 1.60 debye. (http://cccbdb.nist.gov/)

IR Spectrum


	Vibrational model of methylene chloride.

The above IR spectrum is for methylene chloride, and there are many peaks which correspond to certain vibrations in methylene chloride. The peaks around 3100 1/cm is due to the asymmetric stretching between the C-H atoms. The large peak around 1250 1/cm is due to the H-C-H out of plane wagging. The large peak around 1850 1/cm is due to the C-Cl asymmetric stretching. There are other stretches due to other vibrations in methylene chloride, but they are as strong as the ones mentioned.
