Type: MCQ-numerical-Easy-Class 12

What is the carbon–oxygen bond length in phenol, and why is it slightly shorter than that in methanol?

A

136 pm; due to partial double bond character

B

140 pm; because of ionic character

C

136 pm; because of sp3 hybridised state

D

140 pm; due to resonance stabilization

Correct Answer

Option A

Detailed Explanation

The carbon–oxygen bond length in phenol is 136 pm, which is slightly less than in methanol due to partial double bond character from the conjugation of the unshared electron pair of oxygen with the aromatic ring.
