polarity of dichloromethane
Posted: Sat Dec 07, 2019 9:46 am
at the study session last night he said that dichloromethane (CCl2H2) is polar no matter where the Cls are arranged. Can someone explain why this molecule would still be polar?

Essentially a tetrahedral structure can be rotated in different ways that is not accurately depicted in a 2 d structure, so if the H's and Cl's were opposite each other the molecule would still be polar. Imagine that the atoms on the left and right of the C are actually going into and out of the page, but not at 180 degree angles. Because of the tetrahedral structure it wouldn't cancel.
