Question

The restricted rotation about carbon carbon double bond in 2-butene is due to

(a) overlap of one s and sp²-hybridized orbitals

(b) overlap of two sp²-hybridized orbitals

(c) overlap of one p and one sp²-hybridized orbitals

(d) sideways overlap of two p-orbitals.

Answer 1

The correct option is: (d) sideways overlap of two p-orbitals.

Explanation:

Restricted rotation is due to sideways overlap of two p-orbitals.
