Question

A molecule named o-nitrophenol consists of ______________hydrogen bond/s.

(a) intermolecular

(b) intramolecular

(c) both intermolecular and intramolecular

(d) neither intermolecular nor intramolecular

The question was posed to me by my college director while I was bunking the class.

This intriguing question originated from Hydrogen Bonding topic in portion Chemical Bonding and Molecular Structure of Chemistry – Class 11

Answer 1

Correct answer is (b) intramolecular

For explanation I would say: The presence of hydrogen between molecules is intermolecular hydrogen bond and presence of hydrogen bond in the molecule itself is intramolecular hydrogen bond. In o-nitrophenol, there is a hydrogen bond between the hydrogen of the hydroxide group and oxygen.
