Vedclass · Answer

(B) The boiling point of phenolic compounds depends on intermolecular hydrogen bonding.$IV$ (Hydroxybenzene or phenol) has only one $-OH$ group,so it has the lowest boiling point.Among the dihydroxybenzenes $(I, II, III)$,the boiling point increases with the extent of intermolecular hydrogen bonding.$I$ ($1,2$-dihydroxybenzene or catechol) exhibits strong intramolecular hydrogen bonding,which reduces its ability to form intermolecular hydrogen bonds,leading to a lower boiling point compared to $II$ and $III$.$II$ ($1,3$-dihydroxybenzene or resorcinol) has a higher boiling point than $I$ due to more effective intermolecular hydrogen bonding.$III$ ($1,4$-dihydroxybenzene or hydroquinone) has the highest boiling point because its symmetrical structure allows for the most efficient intermolecular hydrogen bonding in the solid state.Therefore,the increasing order is $IV < I < II < III$.
