Questions  

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

a
H2O2
b
HCN
c
Cellulose
d
Concentrated acetic acid

detailed solution

Correct option is C

Cellulose which shows the presence of intramolecular hydrogen bonding . 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 H2O2 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 .

Hence , the correct option is (C).
