a) Which of the compounds CH4 and SiH4 has the stronger inter molecular forces?Explain.
(b) Explain why the boiling points of H2O and H2S show different trends from that of CH4 and SiH4.

(a) S1H4 it has a bigger molecular size and the strength of intermolecular
forces increases with increase in molecular size//it has a higher boiling point.

(b) CH4 and S1H4 have van dar waal?s force only and hence the boiling points increases with increase in molecular size H2O has both van der waal?s forces and hydrogen bonding while H2S has only van der waal?s forces.
