$o$-nitrophenol $(D)$

Vedclass · Answer

(D) The boiling point of these compounds depends on intermolecular hydrogen bonding. $p$-Nitrophenol $(A)$ and $m$-nitrophenol $(B)$ exhibit strong intermolecular hydrogen bonding,leading to higher boiling points. Among these,$p$-nitrophenol has a higher boiling point than $m$-nitrophenol due to better packing and stronger intermolecular forces. $o$-Nitrophenol $(D)$ exhibits intramolecular hydrogen bonding,which reduces the extent of intermolecular hydrogen bonding,resulting in a lower boiling point compared to $p$- and $m$-isomers. Phenol $(C)$ has the lowest boiling point among these as it lacks the additional polar $-NO_2$ group which increases the molecular weight and dipole-dipole interactions. Thus,the order of boiling point is $A > B > D > C$.

The correct order of boiling point for the given compounds is:
