a ) Draw an isomer of C2Cl2 that would result in a non-zero dipole moment, and explain why it has a dipole moment. Also, please draw the dipole moment. The zero dipole moment structure is Cl - C triple bond C - Cl b ) what structural features are required to generate a structure with a zero dipole moment for a molecule containing more than one highly polar bond?

1)The all-cis isomer of 1,2,3,4,5,6-hexafluorocyclohexane (for example, all six fluorines on the same face of the molecule) is one of the most polar non-ionic compounds known. explain why this is the case using chair structure to illustrate. 2) based on the above answer, what would happen to the polarity of the molecule if all the fluorines were on alternating faces (example, 1,3,5 on top face and 2,4,6 on the bottom face)?
