`PH_(3)` has lower boiling point that `NH_(3)`. Why ?

Text Solution

Verified by Experts

In ammonia, `(NH_(3))` the molecules are linked by intermolecular hydrogen bonding which is absent in the molecules of phosphine `(PH_(3))`. Therefore, boiling point of `PH_(3)` is less than that of `NH_(3)`.
