Question

Intramolecular hydrogen bonding is present in:

विकल्प

• 

• HF

• 

• 

Answer 1

Explanation:

Hydrogen bonding occurs within a single molecule. This happens when a molecule contains two functional groups.

HF allows for intermolecular hydrogen bonding but not intramolecular bonding.

In m-nitrophenol and p-nitrophenol, the −NO₂ and −OH groups are widely apart, preventing intramolecular hydrogen bonding. In o-nitrophenol, the −NO₂ and −OH groups on neighbouring carbon atoms generate intramolecular hydrogen bonding.
