Does CIS 1/2 dichloroethylene have a dipole moment?

For example, in 1,2-dichloroethene, each unsaturated carbon atom has a chlorine atom and a hydrogen atom attached to it. … The two C—Cl bond moments of the trans isomer cancel each other, and the compound has no dipole moment. The cis isomer has a dipole moment because the two C—Cl bond moments reinforce each other.

Which of the following product is formed when 1 Bromopropane is allowed to react with alcoholic KOH?
