Question

Intramolecular hydrogen bonding is present in:

A
B
C

HF

D

o-Nitrophenol

Step-by-Step Solution

  1. Definition: Hydrogen bonds can be of two types: intermolecular and intramolecular.
  2. Intramolecular Hydrogen Bond: This type of bond is formed when a hydrogen atom lies in between two highly electronegative atoms (F, O, N) present within the same molecule.
  3. Specific Example: NCERT explicitly cites o-Nitrophenol as an example of intramolecular hydrogen bonding. In this molecule, the hydrogen of the hydroxyl group (-OH) forms a bond with one of the oxygen atoms of the nitro group (-NO2_2) located at the ortho position .
  4. Comparison: HF (Hydrogen Fluoride) exhibits intermolecular hydrogen bonding, where bonds form between different molecules .
