Correct answer

A. (a)−(ii),(b)−(iii),(c)−(iv),(d)−(i)( a ) - ( ii ) , ( b ) - ( iii ) , ( c ) - ( iv ) , ( d ) - ( i )

Step-by-step solution

(a) CH3COOCH2CH3⟶H2SO4/H2OCH3CH2OH{CH}_{3}{COOCH}_{2}{CH}_{3}\overset{{H}_{2}{SO}_{4} / {H}_{2}O}{⟶}{CH}_{3}{CH}_{2}OH (Hydrolysis of ester)

(b) CH3COOCH3⟶DIBAL−HCH3CHO{CH}_{3}{COOCH}_{3}\overset{DIBAL - H}{⟶}{CH}_{3}CHO (Reduction of ester)

(c) CH3≡N⟶SnCl2,HCl/H2OCH3CHO{CH}_{3} ≡ N\overset{{SnCl}_{2}, HCl / {H}_{2}O}{⟶}{CH}_{3}CHO (Reduction followed by hydrolysis)

(d) Match List - I with List - II. List - I (Chemical Reaction) List - II (Reagent used) a CH _ 3 COOCH _ 2 CH _ 3 → CH _ 3 (Nucleophillic addition reaction)
