JEE Advanced levelSingle correct optionDifficulty 3 of 3pl196
Assertion (A): Complete hydrolysis of nylon 2-nylon 6 gives two different amino acids. Reason (R): The polymer chain consists of alternating glycine and 6-aminohexanoic acid units joined by amide links.
ABoth A and R are true and R is the correct explanation of A
BBoth A and R are true but R is not the correct explanation of A
CA is true but R is false
DA is false but R is true
Answer: A
Hydrolysis of the amide links releases the two building blocks, glycine and 6-aminohexanoic acid. The reason describes exactly this alternating structure, so it explains the assertion.
