Which of the following statements is wrong?
1 Single N-N bond is stronger than the single \(\mathrm{P}-\mathrm{P}\) bond
2 \(\mathrm{PH}_{3}\) can act as a ligand in the formation of coordination compound with transition elements
3 \(\mathrm{NO}_{2}\) is paramagnetic in nature
4 Covalency of nitrogen in \(\mathrm{N}_{2} \mathrm{O}_{5}\) is four
Explanation:
Single N-N bond is weaker than the single \(\mathrm{P}-\mathrm{P}\) bond. This is why phosphorous show allotropy but nitrogen does not.

When nitric acid reacts with nitric oxide, a gas is released, which converts \(\mathrm{H}_{2} \mathrm{~S}\) into
1 \(\mathrm{SO}_{4}^{2-}\)
2 \(\mathrm{S}^{2-}\)
3 \(\mathrm{S}\)
4 \(\mathrm{S}_{2} \mathrm{O}_{5}^{2-}\)
Explanation:
When nitric acid \(\left(\mathrm{HNO}_{3}\right)\) reacts with nitric oxide ( \(\mathrm{NO}\) ), \(\mathrm{NO}_{2}\) gas is released which oxidises \(\mathrm{H}_{2} \mathrm{~S}\) into sulphur. \(\begin{aligned}& 2 \mathrm{HNO}_{3}+\mathrm{NO} \rightarrow \mathrm{H}_{2} \mathrm{O}+3 \mathrm{NO}_{2} \\& \mathrm{NO}_{2}+\mathrm{H}_{2} \mathrm{~S} \rightarrow \mathrm{H}_{2} \mathrm{O}+\mathrm{S}+\mathrm{NO}\end{aligned}\)
