A) \[C{{l}_{4}}\]
B) \[Sn{{l}_{4}}\]
C) \[Ge{{l}_{4}}\]
D) \[Pb{{l}_{4}}\]
Correct Answer: D
Solution :
Key Idea: As we go down the group, it becomes difficult to separate electrons present in s sub-shell of valence shell. It is called inert pair effect. The inert pair effect increases as we go down the group. \[\because \]Pb is last member of group 14. \[\therefore \]Among \[C{{I}_{4}},Ge{{I}_{4}},Sn{{I}_{4}}\]and \[Pb{{I}_{4}},Pb{{I}_{4}}\]has doubtful existence.You need to login to perform this action.
