Question

Which of the following best describes the diagram of a molecular orbital?

• A. A bonding $\pi$ orbital
• B. A non-bonding orbital
• C. An antibonding $\sigma$ orbital
• D. An antibonding $\pi$ orbital

Answer 1

The correct option is D An antibonding $\pi$ orbital

An antibonding $\pi$ orbital best describes the diagram of a molecular orbital.

Two p orbitals laterally overlap to form pi bond.

Out of phase combination of these two p orbitals give ${\pi }^{\ast }$ MO.

Hence, the correct option is D.
