Assertion : Overlapping in benzene is \(\mathrm{sp}^{2}-\mathrm{sp}^{2}\) type. Reason : \(\mathrm{C}-\mathrm{C}\) bond length in benzene is 1.3 \( \mathop {\rm{A}}^{\circ} \).
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
Explanation:
Benzene has 6 ' \(\mathrm{C}\) ' atoms with \(\mathrm{sp}^{2}\) hybridisation. The \(\mathrm{C}-\mathrm{C}\) bond length in benzene is \(1.39 \mathrm{~A}\) which is greater than \(\mathrm{C}=\mathrm{C}\) bond length of 1.34 \( \mathop {\rm{A}}^{\circ} \) and less than C-C bond length of 1.54 \( \mathop {\rm{A}}^{\circ} \). So, option (3) is correct.
