Both PH_(3) and NH_(3) are Lewis bases, but basic strength of PH_(3) is less than that of NH_(3). Explain. |
| Answer» Solution :N. atom of `NH_(3)` or .P. atom of `PH_(3)` has a lone pair of ELECTRONS availablefor donation. Hence `NH_(3)` and `PH_(3)` are Lewis bases. The electron pair DENSITY on a larger .P. atom is less than that on smaller .N. atom.Hence `PH_(3)` is a WEAKER BASE. | |
