Match each of the compounds given in Column I with the reaction (s) that they can undergo, given in Column II.

Options

  1. A(A) q,t, (B) q,s, (C) r,t, (D) q,s
  2. B(A) p,q,s, (B) p,q,t, (C) r, (D) q,s
  3. C(A) p,s, (B) q,s, (C) r,t, (D) q,t
  4. D(A) p,q,s, (B) p,q,t, (C) r, (D) q,t

Correct answer

C. (A) p,s, (B) q,s, (C) r,t, (D) q,t

Step-by-step solution

- A. 2-bromobenzofuran: This compound has an alkyl bromide group at a benzylic position. This functional group can undergo p. Nucleophilic substitution to replace the bromine and q. Elimination to form a double bond. - B. Phenylethanol: This is an alcohol. Alcohols can react with acid anhydrides to form esters, which is an ( s ). Esterification reaction. They can also be oxidized to aldehydes or ketones, a process that is also called t. Dehydrogenation. - C. Salicylaldehyde: This compound has two functional groups:
