Question

In methanol, the O-H bond length is smaller than the C-O bond length.

(a) True

(b) False

This question was addressed to me in an internship interview.

The question is from Structures of Functional Groups topic in section Alcohols, Phenols and Ethers of Chemistry – Class 12

Answer 1

Right answer is (a) True

To elaborate: Since hydrogen atom is smaller than the carbon atom and has only 1s orbital, the O-H bond (96pm) is much smaller than the C-O bond (142pm).
