The set of compounds which does not exist, isA. `PbI_(4),BiCl_(5),PH_(5)`B. `XeF_(2),XeF_(3)^(-),XeF_(4)`C. `FeI_(3),CuI_(2),CuCl_(2)`D. `Hg(OH)_(2),Ag_(2)O,V_(2)SO_(4)` |

Answer» Correct Answer - A (a). `PbI_(4)toPbI_(2)+I_(2)` Due to inert pair effect, `Pb^(4+)` converts into `Pb^(2+)` ion, hence `PbI_(4)` does not exist, (b). `BiCl_(5)toBiCl_(3)+Cl_(2)` due to inert pair effect, `Br^(5+)` ion converts into `Bi^(3+)` hence `BiCl_(5)` does not exist. (c). `PH_(5)to` does not exist, because of absence of d-orbital contraction |
