The stability of dihalides of $\mathrm{Si}, \mathrm{Ge}, \mathrm{Sn}$ and $\mathrm{Pb}$ increases steadily in the sequence

Question

Aicharya · Accepted Answer

Due to inert pair effect, the stability of $+2$ oxidation state increases as we move down this group. $	herefore \mathrm{SiX}_2 \ll \mathrm{GeX}_2 \ll \mathrm{SnX}{ }_2 \ll \mathrm{PbX}_2$ Hence, (C) is correct.

The stability of dihalides of $\mathrm{Si}, \mathrm{Ge}, \mathrm{Sn}$ and $\mathrm{Pb}$ increases steadily…
