Question

Intramolecular Hydrogen bonding is formed in

• A. $H_2O$
• B. Salicylaldehyde
• C. $NH_3$
• D. Benzophenone

Answer 1

Answer: (B)

Salicylaldehyde

Answer 2

The hydrogen bonding which takes place within a molecule itself is called intramolecular hydrogen bonding. It takes place in compounds containing two groups such that one group contains a $H$ -atom linked to an electronegative atom and other group contains a highly electronegative atom linked to a lesser electronegative atom, the bond is formed between the $H$ -atom of one group with the more electronegative atom such as $F, O$ or $N$ of the other group.
