Match the List-I with List-II List-I (Reaction) List-II (Mechanism) A. Williamson Synthesis I. Electrophilic addition B. Friedel Craft Reaction II. Free radical substitution C. Bromination of vinyl benzene III. Nucleophilic substitution D. Chlorination of toluene in light IV. Electrophilic substitution Choose the correct answer from the options given below:

Options

  1. AA-III, B-I, C-II, D-IV
  2. BA-III, B-IV, C-II, D-I
  3. CA-III, B-IV, C-I, D-II
  4. DA-I, B-III, C-IV, D-II

Correct answer

C. A-III, B-IV, C-I, D-II

Step-by-step solution

Williamson synthesis involves the reaction of an alkyl halide with a sodium alkoxide to form an ether, which proceeds via a nucleophilic substitution ( S_N2 ) mechanism. Thus, A matches with III. Friedel-Crafts reaction involves the alkylation or acylation of an aromatic ring in the presence of a Lewis acid catalyst, which proceeds via an electrophilic substitution mechanism. Thus, B matches with IV. Bromination of vinyl benzene (styrene) involves the addition of bromine across the carbon-carbon double bond, which
