Answer» Correct Answer - 2 `(a)[NiCl_(2)(PPh_(3))_(2)]` has two unpaired electrons `i.e. e_(g)^(2.2)t_(2g)^(2.1.1)` electron configuration . `(b) [V(CO)_(5)]` has one unpaired electron `i.e. t_(2g)^(2.2.1)e_(g)^(0.0)` electron configuration. `(c ) [Cr(CN)_(6)]^(4-)` has two unpaired electron `i.e. t_(2g)^(2.1.1)e_(g)^(0)` electron configuration. `(d) [Ni(CO)_(4)]` all electrons are paired `i.e. e_(g)^(2.2)t_(2g)^(2.2.2)` electron configuration. |
