Case-Based-V: An element \( \mathrm{Z} \) which is non metal is the largest component of air. \( \mathrm{Z} \) when heated with Hydrogen gas in the presence of \( \mathrm{Fe} \) as catalyst in ratio of \( 1: 3 \) produces a gas \( \mathrm{P} \) . On heating \( \mathrm{Z} \) with \( \mathrm{O}_{2} \), it produces an oxide \( \mathrm{Q} \) . If this \( Q \) reacts with water in presence of air, it will give an acid S that will act as a strong oxidising agent.
Identify element \( (Z) \)
a. \( \mathrm{N}_{2} \)
b. \( \mathrm{Cl}_{2} \)
c. \( \mathrm{S}_{2} \)
d. \( \mathrm{C}_{2} \)
