Which one of the following compound shows the presence of intramolecular hydrogen bond?

ACellulose
Correct Answer
BConcentrated acetic acid
C$$H_2O_2$$
D$$HCN$$

Solution

Cellulose shows the presence of intramolecular hydrogen bonding in them. This is due to the fact that the glucose monomers form straight chains and thus its polymeric structure crowd together showing intramolecular H-bonding.

However $$H_2O_2$$ also show intramolecular hydrogen but its is very weak due to large($$O-OH$$) bond angle which produce repulsions and thus dominant H-bonding is not seen .

Option A is correct.
