Question

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

• A. overlap of two p-orbitals
• B. overlap of one p and one $s{p}^2-$ hybridized orbitals
• C. overlap of two $s{p}^2-$ hybridized orbitals
• D. overlap of one $s$ and one $s{p}^2-$ hybridized orbitals

Answer 1

The correct option is A overlap of two p-orbitals

Restricted rotation about $C-C$ double bond in $2-$butene is not possible due to sideways overlap of $2p-$orbitals.
