Molecular Polarity

Q. There are three different dichloroethylenses(molecular formula C2HCl2) which we can designate X, Y and Z. Compound X has no dipole moment, but compound Z does. Compounds X and Z each combine hydrogen to give the same product: C2H2Cl2(X or Z) + H2 --->ClCh2 ___CH2Cl What are the structures of X, Y and Z? Be sure to include Ione Pair Electrons. Would you expect compound Y to have a dipole moment? Yes No
