Question

methylene chloride is an important industrial solvent, its lewis structure is shown below. classify it as polar or non polar. polar non polar

Explanation:

Step1: Analyze electronegativity difference

Chlorine is more electronegative than carbon and hydrogen. In methylene chloride ($CH_2Cl_2$), the $C - Cl$ bonds are polar due to the electronegativity difference between carbon and chlorine.

Step2: Consider molecular geometry

The molecular geometry of $CH_2Cl_2$ is tetrahedral. The bond - dipoles do not cancel out because the molecule is not symmetrically substituted (two $C - H$ and two $C - Cl$ bonds). The center of the negative charge (from the more electronegative chlorine atoms) and the center of the positive charge (around the carbon - hydrogen region) do not coincide.

Answer:

polar
