Assertion : \( \mathrm{NaCl} \) reacts with concentrated \( \mathrm{H}_{2} \mathrm{SO}_{4} \) to give colourless fumes with pungent smell. But on adding \( \mathrm{MnO}_{2} \) the fumes become
\( \mathrm{P} \) greenish yellow.

W
Reason : \( \mathrm{MnO}_{2} \) oxidises \( \mathrm{HCl} \) to chlorine gas which is greenish yellow.
