Choose the correct option for the stability of dihalides of Si, Ge, Sn and Pb.
Options
- AGeX 2 < SiX 2 < SnX 2 < PbX 2
- BSiX 2 < GeX 2 < PbX 2 < SnX 2
- CSiX 2 < GeX 2 < SnX 2 < PbX 2
- DPbX 2 < SnX 2 < GeX 2 < SiX 2
Correct answer
C. SiX 2 < GeX 2 < SnX 2 < PbX 2
Step-by-step solution
Stability of lower oxidation state increases on moving top to bottom in periodic table and that of higher oxidation state decreases on moving top to bottom in periodic table due to inert pair effect.
