Q36 · CSIR NET Chemistry, December 2016
Paper: CSIR NET December 2016 · Subject: Inorganic Chemistry · Chapter: Acids and Bases · Topic: Acids & Bases – General · Marks: 2 · Difficulty: Medium
Some molecules and their properties in liquid ammonia are given in columns A and B respectively. Match column A with column B
The correct match is
| Column A | Column B |
|---|---|
| (A) $\mathrm{Cl_2}$ | (i) Weak acid |
| (B) $\mathrm{S_8}$ | (ii) Strong acid |
| (C) $\mathrm{CH_3CO_2H}$ | (iii) Disproportionation |
| (D) Urea | (iv) Solvolysis is and disproportionation |
(a)(A)- (i); (B)- (i); (C)- (iii); (D)-(iv)
(b)(A)-(i); (B)- (iii); (C)- (iv); (D)- (i)
(c)(A)-(iii); (B)-(iv); (C)- (i); (D)- (ii)
(d)(A)-(iv); (B)- (iii); (C)-(ii); (D) - (i)
Answer
Answer: D ✓ checked by 4AB · confidence high
Explanation
In liquid NH₃: Cl₂ → NH₂Cl + NH₄Cl (solvolysis and disproportionation, iv); S₈ disproportionates to sulfide and imides (iii); CH₃CO₂H is fully ionised — a strong acid (ii); urea is a weak acid (i).
