Question

In benzene, 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

Answer: (D)

In benzene, there is one $s p^{2}-s p^{2} \sigma$-bond, one $s p^{2}-s p^{2}, \pi$-bond and one $p-p \pi$-bond.
