PH3 is phosphine gas...........

Explanation:

Phosphine is the phosphorus analogue of ammonia. Unlike ammonia, phosphine is not a significant Bronsted base.

The boiling point of phosphine is 87.7 C. The boiling point of ammonia is 33.4 C. Can you explain this difference in volatility on the basis of hydrogen-bonding?
