MHTCET 23 Apr 2025 Shift 2 Paper

Concept:The key is to identify which polymer is designed to be biodegradable.Explanation:$\text{Nylon-6}$ is a synthetic polyamide and is not biodegradable.$\text{Nylon-6,6}$ is made from adipic acid and hexamethylenediamine, so it is also non-biodegradable.$\text{Nylon-2-nylon-6}$ is a copolymer of glycine and aminocaproic acid.Since glycine is a naturally occurring amino acid, this copolymer is biodegradable.$\text{HDP}$ (high-density polyethylene) is a polyolefin and is not biodegradable.Answer:Option C: $\text{Nylon-2-nylon-6}$
