I think Mr Alow is gently suggesting that you have copied it down incorrectly (chromo instead of chloro)

sorry. i meant to write chloro*.

how would you answer it if its dichloro? Sorry for calling you a dumbass

For a molecule to have no net dipole the contribution of the individual polar bonds must cancel out. You need to look for the most symmetric structure (and the one where the C-Cl bonds are in the same direction with opposite signs).

I see so would it be A as the polar bonds are attached to the same Cabon atom on the C=C double bond, therefore would cancel out?
Does the shape of the molecule affect polarity?
