Account for the following : PCl_(5) is more covalent than PCl_(3). |
| Answer» Solution :The OXIDATION state of P in `PCl_(5)` is +5 and that in `PCl_(3)` is +3. Since ELEMENTS in the +5 oxidation state have less TENDENCY to LOSE electrons than in the +3 oxidation state, therefore, P in the +5 oxidation state has more tendency to share its electrons with Cl than in the +3 oxidation state. THUS, `PCl_(5)` is more covalent than `PCl_(3)`. | |
