Polar or nonpolar

Postby Lauryn Shinno 2H » Sun Nov 18, 2018 8:41 am

For molecules, such as CH2Cl2, that can be drawn in multiple ways, how do you know which one is correct? For example, you could put the two hydrogens and two chlorines next to each other around the central carbon or you could alternate them. This would affect whether the molecule is polar or not, so which do you use?

I think for molecules like that, it is possible for it to have different isomers which are both polar and nonpolar. My TA did an example in discussion with C2F2H2, a similar molecule, and there were three isomers, one of which was nonpolar because the polarities cancel each other out. This isomer then would behave differently than the other two polar isomers.
