Which one of the following compounds shown the presence of intramolecular hydrogen bond?
(1) H2O2 (2) HCN (3) Cellulose (4) Concentrated acetic acid
In Cellulose Intramolecular hydrogen bonding is present , 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 .
