On being slowly passed through water, `PH_(3)` forms bubbles but `NH_(3)` dissolves. Why is it so ?

Text Solution

Verified by Experts

`N - H` bond is more polar than `P - H` bond. Hence, `NH_(3)` forms hydrogen bonds with `H_(2)O` molecules and hence dissolves in it whereas `PH_(3)` does not dissolve and forms bubbles.
