Assertion : \(\mathrm{H}_{2} \mathrm{~S}\) is stronger acid than \(\mathrm{PH}_{3}\) Reason : \(\mathrm{S}\) is more electronegative than \(\mathrm{P}\), conjugate base \(\mathrm{HS}^{-}\)is more stable than \(\mathrm{H}_{2} \mathrm{P}^{-}\).
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.
Explanation:
\(\mathrm{H}_{2} \mathrm{~S}_{(\mathrm{g})}+\mathrm{aq} \rightarrow \mathrm{HS}_{(\mathrm{aq})}^{-}+\mathrm{H}_{\text {(aq) }}^{+}\) \(\mathrm{PH}_{3(\mathrm{~g})}+\mathrm{aq} \rightarrow \mathrm{H}_{2} \mathrm{P}_{(\mathrm{aq})}^{-}+\mathrm{H}_{(\mathrm{aq})}^{+}\) As \(\mathrm{S}\) is more electronegative than \(\mathrm{P}\), conjugate base \(\mathrm{HS}^{-}\)is more stable than \(\mathrm{H}_{2} \mathrm{P}^{-}\). Hence, \(\mathrm{H}_{2} \mathrm{~S}\) is stronger acid than \(\mathrm{PH}_{3}\). So option (1) is correct.

Central atom is \({\rm{s}}{{\rm{p}}^{\rm{3}}}{\rm{d}}\)-hybridised in
\({\rm{PC}}{{\rm{l}}_{\rm{5}}}{\rm{,}}\,\,{\rm{s}}{{\rm{p}}^{\rm{3}}}{\rm{d}}\) - hybridised \(\mathrm{P}\), no lone pair \({\rm{Br}}{{\rm{F}}_{\rm{3}}}{\rm{,}}\,\,{\rm{s}}{{\rm{p}}^{\rm{3}}}{\rm{d}}\) - hybridised \(\mathrm{Br}\), two lone pairs \({\rm{Xe}}{{\rm{F}}_{\rm{2}}}{\rm{,}}\,\,{\rm{s}}{{\rm{p}}^{\rm{3}}}{\rm{d}}\) - hybridised Xe, three lone pairs

Assertion : Moelcular nitrogen is less reactive than molecular oxygen. Reason : The bond length of \(\mathrm{N}_{2}\) is shorter than that of oxygen.
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.
Explanation:
\(\mathrm{N}_{2}\) is less reactive than that of \(\mathrm{O}_{2}\) because nitrogen has high dissociation energy in comparison to oxygen so, its reactivity is less. Also, bond length of nitrogen is shroter than oxygen because of presence of triple bond between nitrogen atoms. Hence, both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
