Which among `CH_(4), SiH_(4), GeH_(4)`, and `SnH_(4)` is the most volatile?

The correct order for melting point and boiling point of IV group hydrides respectively I) CH_(4) lt SiH_(4) lt GeH_(4) lt SnH_(4) II) CH_(4) gt SiH_(4) lt GeH_(4) lt SnH_(4) III) SnH_(4) lt GeH_(4) lt SiH_(4) lt CH_(4) IV) CH_(4) lt SiH_(4) gt GeH_(4) gt SnH_(4)

Among MgSO_4, CaSO_4, SrSO_4 and BaSO_4 , which one is most soluble in water ?

SiH_(4)+NaOH +H_(2)O to X +3H_(2) X in the above reaction is

Which is more acidic among HClO_(4) and HIO_(4) ? Why ?

The difference in properties of CH_(4) and SiH_(4) is due to :

Consider the hydrides of group 14 elements 1. CH_4 2. SiH_4 3. GeH_4 4. SnH_4 The correct sequence of thermal stability is
