Question

The number of $s{p}^2$ hybrid orbitals in molecule of benzene is:

• A. $18$
• B. $24$
• C. $6$
• D. $12$

Answer 1

The correct option is A $18$

Benzene $\left(C_6{H}_6\right)$ has 6 $s{p}^2$ hybridized carbons. Each carbon has 3 $\sigma$-bonds and 1 $\pi$-bond. 3 $\sigma$-bonds means that there are 3 $s{p}^2$ hybrid orbitals for each carbon. Hence, the total number of $s{p}^2$ hybrid orbitals is 18.
