A) \[C{{H}_{4}}>Si{{H}_{4}}>Ge{{H}_{4}}>Sn{{H}_{4}}>Pb{{H}_{4}}\]
B) \[C{{H}_{4}}<Si{{H}_{4}}<Ge{{H}_{4}}<Sn{{H}_{4}}<Pb{{H}_{4}}\]
C) \[C{{H}_{4}}>Sn{{H}_{4}}>Ge{{H}_{4}}>Si{{H}_{4}}>Pb{{H}_{4}}\]
D) None of the above
Correct Answer: A
Solution :
The stability of hydrides of carbon family decreases down the group, hence order is \[C{{H}_{4}}>Si{{H}_{4}}>Ge{{H}_{4}}>Sn{{H}_{4}}>Pb{{H}_{4}}\]
