Question

NH3 has a much higher boiling point than PH3 does. Why?

Answer 1

NH3 is a molecule which exhibits the hydrogen bonding between the NH3 molecules.....

In PH3 there is no hydrogen bonding

so the boiling points of NH3 is more than PH3.

❤⭐..REASON:-..⭐❤

• ❤.. Unlike ${NH3,PH3}$ molecules are not associated through hydrogen bonding in liquid state.
• ❤.. That is why the boiling point of ${PH3}$ is lower than${NH3}$.
