The stability of dihalides of Si, Ge, Sn and Pb increases steadily in the sequence

Question

The stability of dihalides of Si, Ge, Sn and Pb increases steadily in the sequence (A) GeX2 << SiX2 << SnX2 << PbX2 (B) SiX2 << GeX2 << PbX << SnX2 (C) SiX2 << GeX2 << SnX2 << PbX2 (D) PbX2 << SnX2 << GeX2 << SiX2

Due to inert pair effect, the stability of +2 oxidation state increases as we move down this group. ∴SiX2 << GeX2 << SnX2 << PbX2 Hence, (3) is correct.

Q. The stability of dihalides of $S i, G e, S n$ and $P b$ increases steadily in the sequence

$G e X_{2} << S i X_{2} << S n X_{2} << P b X_{2}$

$S i X_{2} << G e X_{2} << P b X << S n X_{2}$

$S i X_{2} << G e X_{2} << S n X_{2} << P b X_{2}$

$P b X_{2} << S n X_{2} << G e X_{2} << S i X_{2}$

Due to inert pair effect, the stability of $+ 2$ oxidation state increases as we move down this group.
$∴ S i X_{2} << G e X_{2} << S n X_{2} << P b X_{2}$
Hence, (3) is correct.

Q. The stability of dihalides of Si,Ge,Sn and Pb increases steadily in the sequence

GeX2​<<SiX2​<<SnX2​<<PbX2​

SiX2​<<GeX2​<<PbX<<SnX2​

SiX2​<<GeX2​<<SnX2​<<PbX2​

PbX2​<<SnX2​<<GeX2​<<SiX2​
