The correct statements with respect to halides of group 14 elements are
I. Both 
and 
undergo hydrolysis
II. 
is more stable than 
III. 
is less stable than 
IV. Stability of dihalides decreases down the group.
Text Solution
Verified by ExpertsC
does not undergo hydrolysis since 
does not have 'd' orbital to accept the electrons from donor. 
is incorrect.
GP. 14 elements have 4 electrons in their valence shells. So, 
and 
are the common oxidate states (O.S.) from 
to 
. However, the stability of (+4) O.S. decreases from 
to 
due to inert pair effect. Therefore, Ge forms stable compound in (+4) O.S. and 
in (+2) O.S. 
(II) & (III) are correct.
Stability of dihalides increases down the group. 
(IV) is incorrect.
