$p > m > o$

Vedclass · Answer

(B) For $o$-nitrophenol,hydrogen bonding is intramolecular,i.e.,confined to the same molecule.For $m$-nitrophenol and $p$-nitrophenol,hydrogen bonding is intermolecular,occurring between different molecules.Therefore,$p$-nitrophenol has the highest melting point due to strong intermolecular hydrogen bonding and symmetrical packing,followed by $m$-nitrophenol,while $o$-nitrophenol has the lowest melting point.The correct order of melting point is $p > m > o$.
