Q. The stability of hydrides of carbon family is in the order
A) $CH_{4} > SiH_{4} > GeH_{4} > SnH_{4} > PbH_{4}$
B) $CH_{4} < SiH_{4} < GeH_{4} < SnH_{4} < PbH_{4}$
C) $CH_{4} > SnH_{4} > GeH_{4} > SiH_{4} > PbH_{4}$
D) None of the above
Explanation
(a)
The stability of hydrides of carbon family decreases down the group, hence order is
$CH_{4}\ > SiH_{4}\ > GeH_{4} >$ $SnH_{4}\ > PbH_{4}$
