CHXI11:THE P-BLOCK ELEMENTS

316357 Chlorine is prepared in the laboratory by the action of

1 \(\mathrm{Zn}\) and \(\mathrm{HCl}\)
2 \(\mathrm{CaCO}_{3}\) and \(\mathrm{HCl}\)
3 \(\mathrm{Pb}\left(\mathrm{NO}_{3}\right)_{2}\) and \(\mathrm{HCl}\)
4 \(\mathrm{MnO}_{2}\) and \(\mathrm{HCl}\)
CHXI11:THE P-BLOCK ELEMENTS

316358 Assertion :
Chlorine undergoes disproportionation reaction in alkaline medium.
Reason :
\(\mathrm{Cl}_{2}\) is an oxidising agent.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but Reason is correct.
CHXI11:THE P-BLOCK ELEMENTS

316359 Concentrated hydrochloric acid when kept in open air sometimes produces a cloud of white fumes. The explanation for it is that

1 Concentrated hydrochloric acid emits strongly smelling HCl gas all the time
2 Oxygen in air reacts with the emitted HCl gas to form a cloud of chlorine gas
3 Strong affinity of HCl gas for moisture in air results in forming of droplets of liquid solution which appears like a cloudy smoke
4 Due to strong affinity for water, concentrated hydrochloric acid pulls moisture of air towards itself. This moisture forms droplets of water and hence the cloud.
CHXI11:THE P-BLOCK ELEMENTS

316360 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 greenish yellow.
Reason :
\(\mathrm{MnO}_{2}\) oxidises \(\mathrm{HCl}\) to chlorine gas which is greenish yellow.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect.
