While separating a mixture of $o-$ and $p-$nitrophenols by steam distillation,name the isomer which will be steam volatile. Give reason.
(N/A) $o-$Nitrophenol is steam volatile.
Reason: $o-$Nitrophenol exhibits intramolecular $H-$bonding,which restricts its association with other molecules. In contrast,$p-$nitrophenol exhibits intermolecular $H-$bonding,leading to strong association between its molecules. Due to this,$o-$nitrophenol has a lower boiling point and is more steam volatile than $p-$nitrophenol.
