D
| Column I | Column II |
|---|---|
| (A) (see structure) | (p) Nucleophilic substitution |
| (B) (see structure) | (q) Electrophilic substitution |
| (C) (see structure) | (r) Dehydration |
| (D) (see structure) | (s) Nucleophilic addition |
| (t) Carbanion |
Answer: A → III, A → IV, A → V, B → I, B → IV, C → III, C → IV, D → II, D → III
Solution
Based on the source solution:
(A) Involves dehydration (r), nucleophilic addition (s), and carbanion intermediate (t). Matches: r, s, t
(B) Involves nucleophilic substitution (p) and nucleophilic addition (s). Matches: p, s
(C) Involves dehydration (r) and nucleophilic addition (s). Matches: r, s
(D) Involves electrophilic substitution (q) and dehydration (r). Matches: q, r
The specific mechanisms depend on the structures shown in the images.
