Question

Which of the following molecules show the presence of intramolecular hydrogen bonding?
(a) Cellulose
(b) $HCN$
(c) Concentrated Acetic Acid
(d) ${H_2}{O_2}$

Answer 1

Hint: In order to answer this question, to know the given correct option that shows the presence of intramolecular hydrogen bonding, we will write the correct option i.e. is the most abundant organic polymer on Earth, and we will discuss more about it.

Complete answer:
Cellulose shows the presence of intra molecule 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 Hydrogen-Bonding, however $H_2O_2$ also show intramolecular hydrogen but it is very weak due to large \[\left( {O - OH} \right)\] bond angle which produce repulsions and thus dominant Hydrogen-bonding is not seen.
Cellulose is the most abundant organic polymer on Earth. The cellulose content of cotton fiber is \[90\% \] , that of wood is \[40-50\% \] , and that of dried hemp is approximately $57\% $ . Cellulose is mainly used to produce paperboard and paper. Smaller quantities are converted into a wide variety of derivative products such as cellophane and rayon.
Cellulose is a complex carbohydrate consisting of oxygen, carbon, and hydrogen. It is chiral, tasteless and has no odour. A French chemist by name Anselme Payen was the first to discover cellulose in the year 1838. This organic compound is water-soluble and biodegradable.
Hence, the correct option is (A).

Note:
At temperatures above $350^oC$, cellulose undergoes thermolysis (also called ‘pyrolysis’), decomposing into solid char, vapors, aerosols, and gases such as carbon dioxide.
The basic structural component of plant cell walls, cellulose comprises about 33 percent of all vegetable matter (90 percent of cotton and 50 percent of wood are cellulose) and is the most abundant of all naturally occurring organic compounds.
