Q20 · CSIR-NET Chemistry, June 2016

Paper: CSIR-NET June 2016 · Subject: Inorganic Chemistry · Chapter: Acids and Bases · Topic: Acids & Bases – General · Marks: 2 · Difficulty: Easy

Consider the following reactions:
\[ \begin{array}{ll} \text{(A) } \mathrm{NOCl}+\mathrm{Sn}\,\mathrm{N}_{2}\mathrm{O}_{4} & \text{(B) } \mathrm{NOCl}+\mathrm{AgNO}_{3} \rightarrow \\ \text{(C) } \mathrm{NOCl}+\mathrm{BrF}_{3} \rightarrow & \text{(D) } \mathrm{NOCl}+\mathrm{SbCl}_{5} \rightarrow \end{array} \]
Reactions which will give $[\mathrm{NO}]^{+}$as a major product are:
(a)A and B
(b)C and D
(c)A and C
(d)B and D
Answer
Answer: B ✓ checked by 4AB · confidence high

The source book printed D; on checking, B is correct — see the explanation.

Explanation
The halide acceptors BrF₃ and SbCl₅ take the halide from NOCl, leaving NO⁺ salts (e.g. NO⁺SbCl₆⁻). AgNO₃ gives AgCl + N₂O₄, and Sn gives SnCl₄ + NO. C and D (b).
