Chemical Bonding and Molecular Structure question

2024 · 1 Feb · Shift 1 · Q14

JEE MainChemistryChemical Bonding and Molecular StructureMCQ+4 / −1
Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): PH3\mathrm{PH}_3PH3​ has lower boiling point than NH3\mathrm{NH}_3NH3​. Reason (R) : In liquid state NH3\mathrm{NH}_3NH3​ molecules are associated through vander Waal's forces, but PH3\mathrm{PH}_3PH3​ molecules are associated through hydrogen bonding. In the light of the above statements, choose the most appropriate answer from the options given below :
  1. A
    Both (A) and (R) are correct and (R) is the correct explanation of (A)
  2. B
    (A) is not correct but (R) is correct
  3. C
    (A) is correct but (R) is not correct
  4. D
    Both (A)(\mathbf{A})(A) and (R)(\mathbf{R})(R) are correct but (R)(\mathbf{R})(R) is not the correct explanation of (A)(\mathbf{A})(A)
