Verified Solution • 2025–26 Session moderate

The stability of dihalides of

S i, G e, S n

and

P b

increases steadily in the sequence :

Accepted Answer

Reductance of valence shell electrons to participate in bonding is called inert pair effect. The stability of lower oxidation state (

+ 2

for group

14

element) increases on going down the group. So the correct order is

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