PH_(3) forms bubbles when passed slowly in water but NH_(3) dissolves. Explain why ? |
| Answer» Solution :DUE ot HIGH electronegativity (3.0) and SMALL size of `N,NH_(3)` forms H-bonds with water and H-bonds with water and hence it is water soluble. On the other hand, due to its LOWER electronegativity (2.1) of P and its bigger size than `N,PH_(3)` does not form H-bonds with `H_(2)O`. As a result, it does not dissolve in `H_(2)O` and hence escapes as bubbles. | |
