vii. The stability of dihalides of ` Si, Ge , Sn` and Pb increases steadily in the sequence :A. `PbX_(2) lt lt SnX_(2) lt lt GeX_(2) lt lt SiX_(2)`B. `GeX_(2) lt lt SiX_(2) lt lt SnX_(2) lt lt PbX_(2)`C. `SiX_(2) lt lt GeX_(2) lt lt PbX_(2) lt lt SnX_(2)`D. `SiX_(2) lt lt GeX_(2) lt lt SnX_(2) lt lt PbX_(2)` |

Answer» Correct Answer - D Due to the inert pair effect (the reluctance of `ns^(2)` electrons of outermost shell to participate in bonding) the stability of `M^(3+)` ions (of group 14 elements ) increases as we down the group. |
