Phosphorus and Its Compounds
CHXI11:THE P-BLOCK ELEMENTS

316852 Assertion :
\(\mathrm{NH}_{3}\) and \(\mathrm{PH}_{3}\) differ from each other in their reaction with \(\mathrm{CuSO}_{4}\) or \(\mathrm{AgNO}_{3}\).
Reason :
\(\mathrm{PH}_{3}\) acts as oxidising agent in these reactions but \(\mathrm{NH}_{3}\) does not.

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

316853 \(\mathrm{PH}_{3}\) forms bubbles when passed slowly in water but \(\mathrm{NH}_{3}\) dissolves because

1 \(\mathrm{PH}_{3}\) is lighter gas so it bubbles out
2 \(\mathrm{PH}_{3}\) hates water hence it bubbles out
3 \(\mathrm{PH}_{3}\) cannot form hydrogen bond with water so it bubbles out.
4 \(\mathrm{PH}_{3}\) is covalent hence it bubbles out.
