JEE Main 2024 Chemistry question

The incorrect statement regarding the geometrical isomers of 2-butene is:

(A)cis-2-butene and trans-2-butene are not interconvertible at room temperature.
(B)cis-2-butene has less dipole moment than trans-2-butene.Correct
(C)trans-2-butene is more stable than cis-2-butene.
(D)cis-2-butene and trans-2-butene are stereoisomers.

Answer: (B)

Solution

cis-2-butene has a net dipole moment while trans-2-butene has zero, so (B) is incorrect.
