Question

In benzyne, the triple bond consists of:

• A. one $sp-sp$ sigma bond and two $p-p$ pi bonds
• B. two $sp-sp$ sigma bonds and one $p-p$ pi bond
• C. one ${sp}^2-{sp}^2$ sigma bond, one $p-p$ pi bond
• D. one ${sp}^2-{sp}^2$ sigma bond, one ${sp}^2-{sp}^2$ pi bond and one $p-p$ pi bond

Answer 1

The correct option is D one ${sp}^2-{sp}^2$ sigma bond, one ${sp}^2-{sp}^2$ pi bond and one $p-p$ pi bond

In benzene, the triple bond consists of one ${sp}^2-{sp}^2$ $\sigma$-bond, one ${sp}^2-{sp}^2$, $\pi$-bond and one $p-p$ $\pi$-bond.

Option D is correct.
