Assertion (A): In molecule, the rotation about carbon-carbon double bond is restricted
Reason (R): Rotation of one fragment with respect to other interferes with maximum overlap of -orbitals.
Reason (R): Rotation of one fragment with respect to other interferes with maximum overlap of -orbitals.
View answer and explanation
Correct option: A
Both and are correct ; is the correct explanation of .
Option A (Both A and R are correct ; R is the correct explanation of A) is correct because the restricted rotation around the C=C double bond is due to the interference with the maximum overlap of p-orbitals.
