Question

Out of the following compounds, which will have a zero dipole moment? (a) 1, 1-dichloroethylene(b) cis-1, 2-dichloroethylene(c) trans-1, 2-dichloroethylene(d) None of these compounds

Answer 1

Trans 1,2 dichloro ethylene will have zero dipole moment because,

If we see the structure of the compound the two chlorine and hydrogen atoms orient in opposite way on adjacent carbons and cancel each other.Hence it have zero dipole moment.

Sorry i cant draw the structure here!

Hope this helps you.

Answer 2

Answer:

Explanation:

Trans 1,2 di-chloro ethylene will have zero dipole moment because, in the structure of the compound ,the two chlorine and hydrogen atoms orient in opposite way on adjacent carbons and cancel each other. Thus it will have zero dipole moment.
