JEE Main Chemistry question

Dipole moment is exhibited by:

(A)1,4-dichlorobenzene
(B)1,2-dichlorobenzeneCorrect
(C)trans-1,2-dichloroethene
(D)trans-1,2-dichloro-2-butene

Answer: (B)

Solution

In 1,4-dichlorobenzene (para), the two C–Cl bond dipoles point in exactly opposite directions and cancel, giving zero net dipole moment; likewise, the trans-alkenes in (C) and (D) have their two C–Cl dipoles positioned symmetrically opposite across the double bond and also cancel. In
