The stability of dihalides of Si, Ge, Sn and Pb increases steadily...

The stability of dihalides of

\mathrm{Si}, \mathrm{Ge}, \mathrm{Sn}

and

\mathrm{Pb}

increases steadily in the sequence

Options

A $\mathrm{GeX}_2 \ll \mathrm{SiX}_2 \ll \mathrm{SnX_2} \ll \mathrm{PbX}_2$
B $\mathrm{SiX}_2 \ll \mathrm{GeX}_2 \ll \mathrm{PbX}_2 \ll \mathrm{SnX}{ }_2$
C $\mathrm{SiX}_2 \ll \mathrm{GeX}_2 \ll \mathrm{SnX}_2 \ll \mathrm{PbX}_2$
D $\mathrm{PbX}_2 \ll \mathrm{SnX}_2 \ll \mathrm{GeX}_2 \ll \mathrm{SiX}_2$

Correct answer

C. $\mathrm{SiX}_2 \ll \mathrm{GeX}_2 \ll \mathrm{SnX}_2 \ll \mathrm{PbX}_2$

Step-by-step solution

Due to inert pair effect, the stability of

+2

oxidation state increases as we move down this group.

\therefore \mathrm{SiX}_2 \ll \mathrm{GeX}_2 \ll \mathrm{SnX}{ }_2 \ll \mathrm{PbX}_2

Hence, (C) is correct.
