Vedclass · Answer

(D) $1$. The $m.p.$ of $H_2O$ and $NH_3$ are indeed the highest in their respective groups ($Group$ $16$ and $Group$ $15$) due to the presence of strong intermolecular $H$-bonding.$2$. The $b.p.$ of hydrides of $Group$ $14$ $(CH_4, SiH_4, GeH_4, SnH_4)$ increases with increasing molecular mass due to stronger van der Waals forces. Thus,$CH_4$ has the lowest $b.p.$$3$. Formic acid $(HCOOH)$ exists as a dimer in the vapor state and in non-polar solvents due to intermolecular $H$-bonding.$4$. Since all statements are correct,the correct option is $D$.
