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
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
The correct match is
(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).
