Step 1: Substrate Analysis — The peptide Asn-Ser (Asparagine-Serine) possesses a primary amino group (at the N-terminal end) and a primary alcohol group (on the serine side chain).
Step 2: Acetylation Reaction — Under basic conditions with acetic anhydride (), both the amino () and alcohol () groups will be acetylated.
Step 3: Resulting Structure — Structure (b) accurately reflects the derivative where both these groups have undergone substitution. Correct option is (b).
Key Point: Tertiary amines like triethylamine () act as catalysts/bases in these nucleophilic substitution reactions.
