Question

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

(1) cis-2-butene and trans-2-butene are not interconvertible at room temperature. 

(2) cis-2-butene has less dipole moment than trans-2-butene. 

(3) trans-2-butene is more stable than cis-2-butene. 

(4) cis-2-butene and trans-2-butene are stereoisomers.

Answer 1

Correct option is (2) cis-2-butene has less dipole moment than trans-2-butene. 

Cis–but–2–ene has higher Dipole moment than trans–but–2–ene.
