Question

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R).

Assertion (A): PH₃ has a lower boiling point than NH₃.

Reason (R): In the liquid state, NH₃ molecules are associated through vander waal’s forces, but PH₃ molecules are associated through hydrogen bonding

In the light of the above statements, choose the most appropriate answer from the options given below:
