Question

$P{H}_3$ forms bubbles when passed slowly in water but $N{H}_3$ dissolves. Explain why?

Answer 1

* N- H bond is more polar than P-H bond

* $N{H}_3$ is highly soluble in water because of its ability to form hydrogen bond with water due to its high electronegativity.

* $P{H}_3$ is very less polar compound and cannot form hydrogen bond with water. Therefore, it is not much soluble in water and escapes as gas,
forming bubbles.
