Vedclass · Answer

(A) Volatility is inversely proportional to the boiling point of a substance.For the hydrides of group $14$ elements $(CH_4, SiH_4, GeH_4, SnH_4)$,the molecular mass increases as we move down the group from $C$ to $Sn$.As the molecular mass increases,the magnitude of van der Waals forces of attraction increases,leading to an increase in the boiling point.Therefore,the boiling point order is $CH_4 Since $CH_4$ has the lowest boiling point,it is the most volatile compound among the given options.

Which of the following compounds is the most volatile among $CH_4, SiH_4, GeH_4, SnH_4$?
