Question

The number of ${\mathrm{sp}}^2$ hybrid orbitals in molecule of benzene is

• A. 18
• B. 24
• C. 6
• D. 12

Answer 1

The correct option is A

18

Explanation for correct answer:-

Option (A) 18:

${\mathbf{sp}}^{\mathbf{2}}$ hybrid orbitals in Benzene:-

• Benzene has 6 carbon atoms and 6 hydrogen atoms and has a structural formula of ${\mathrm{C}}_6{\mathrm{H}}_6$.

• Now each of these 6 carbon atoms is ${\mathrm{sp}}^2$hybridised, and each carbon has 3 ${\mathrm{sp}}^2$hybrid orbitals.
• Thus the total number of hybrid orbitals in benzene is $6\times 3=18$

Therefore, The number of ${\mathrm{sp}}^2$ hybrid orbitals in molecule of benzene is option (A)$18$
