Choose the correct answer from the options given below:
| 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
- AA-III, B-I, C-II, D-IV
- BA-III, B-IV, C-II, D-I
- CA-III, B-IV, C-I, D-II
- 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 () 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 proceeds via an electrophilic addition mechanism. Thus, C matches with I.
Chlorination of toluene in the presence of sunlight (or UV light) involves the substitution of hydrogen atoms in the methyl group by chlorine, which proceeds via a free radical substitution mechanism. Thus, D matches with II.
The correct matching is A-III, B-IV, C-I, D-II.
