Chemistry - Biomolecules Question with Solution | TestHub

Starch is a polysaccharide composed of repeating $\alpha$-D-glucose units, which form amylose and amylopectin. Thus, statement (A) is correct.

Nylon-6 is synthesized from caprolactam and Nylon-6,6 is synthesized from hexamethylenediamine and adipic acid. Both are polyamides and are classified as condensation polymers. Thus, statement (B) is incorrect.

Natural rubber is a linear polymer of isoprene (2-methyl-1,3-butadiene) and is also called cis-1,4-polyisoprene. Thus, statement (C) is correct.

Bakelite is a condensation polymer obtained from the reaction between phenol and formaldehyde, not acetaldehyde. Thus, statement (D) is incorrect.

Answer: Strach is composed of repeating $\alpha$–D glucose units; Isoprene is the monomer unit of natural rubber
