Question

Match the column I with column II and mark the appropriate choice.

Column I	Column II
(A) Clemmensen reduction	(i) $N{H}_{2}N{H}_2,KOH/△$
(B) Wolff-kishner	(ii) $Zn-Hg+conc.HCl$
(C) Iodoform reaction	(iii) $H_2,Pd/Pt/Ni$
(D) Catalytic hydrogenation	(iv) $NaOH+I_2$

• A. (A)-(i) (B)-(iii) (C)-(ii) (D)-(iv)
• B. (A)-(iii) (B)-(iv) (C)-(i) (D)-(ii)
• C. (A)-(ii) (B)-(i) (C)-(iv) (D)-(iii)
• D. (A)-(iv) (B)-(i) (C)-(ii) (D)-(iii)

Answer 1

The correct option is C (A)-(ii) (B)-(i) (C)-(iv) (D)-(iii)

Clemmensen reduction:$Zn-Hg+\text{conc.}HCl$
Clemmensen reduction reduces Aldehydes and ketones to corresponding hydrocarbons.

Wolff-kishner: $N{H}_{2}N{H}_2,KOH/△$
It reduces aldehydes and ketones to corresponding hydrocarbons.

Iodoform reaction : $I_2+NaOH$
Iodoform reaction used for the identifiacation of methyl ketone.

Catalytic hydrogenation: $H_2,Pd/Pt/Ni$
It reduces alkene to alkane and aldehyde and ketones to alcohols.

Hence, the correct answer is option (c).
