LoginWhich of the following is not a correct reason for the C-O bond length in phenol to be less than that in methanol?
(a) Partial double bond character of C-O bond
(b) Conjugation of lone pair of electrons with the aromatic ring
(c) sp^2 hybridised sate of carbon of C-O bond
(d) Repulsion between the electron lone pairs of oxygen
I had been asked this question by my school teacher while I was bunking the class.
Query is from Structures of Functional Groups topic in portion Alcohols, Phenols and Ethers of Chemistry – Class 12
Chemistry – Class 12 Alcohols in Chemistry – Class 12 3 years ago
The CORRECT choice is (d) Repulsion between the electron lone PAIRS of oxygen
The BEST explanation: The two lone pairs of ELECTRONS of oxygen are present in OH groups of both phenol and methanol and has an effect on the C-O-H bond angle and not the C-O bond length.
