Match List-I with List-II: List-I (Reaction) (a) (benzophenone) (b) Alkene carbonyl (oxidative cleavage) (c) carbonyl (oxidation) (d) List-II (Reagents/Condition) (i) , anhyd. (ii) (iii) /, (iv) (1) , (2) Choose the correct option:
Answer: (B) (B) (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii). \textbf{Answer:} (B) (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii).
- A.(A) (a)-(iii), (b)-(i), (c)-(ii), (d)-(iv)
- B.(B) (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)✓
- C.(C) (a)-(i), (b)-(iv), (c)-(ii), (d)-(iii)
- D.(D) (a)-(iv), (b)-(i), (c)-(iii), (d)-(ii)
Correct Answer
(B) (B) (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii)
Solution & Explanation
\textbf{Answer:} (B) (a)-(iv), (b)-(i), (c)-(ii), (d)-(iii). \textbf{Solution:} (b)-(i): benzene undergoes Friedel-Crafts acylation with /anhyd. to give benzophenone. (d)-(iii): the side chain of ethylbenzene is oxidised by /, to benzoic acid. (c)-(ii): phenol is oxidised by to a carbonyl (quinone-type) product, and (a)-(iv): an alkene is cleaved by ozonolysis [(1) , (2) ] to carbonyl compounds. This gives option (B).
