Vedclass · Answer

(C) The boiling point $(BP)$ depends on the strength of intermolecular forces. $H_2O_2$ has the highest boiling point due to strong hydrogen bonding and high molecular mass. Between $D_2O$ and $H_2O$,$D_2O$ has a higher boiling point $(101.4 \ ^\circ C)$ than $H_2O$ $(100 \ ^\circ C)$ due to stronger hydrogen bonding and higher molecular mass. Between $H_2$ and $D_2$,both are non-polar molecules held by weak van der Waals forces. $D_2$ has a higher molecular mass than $H_2$,so it has a higher boiling point. Thus,the correct order is $H_2O_2 > D_2O > H_2O > D_2 > H_2$.
