Question

Intramolecular hydrogen bonding is found in :
(a) p-nitrophenol
(b) m-nitrophenol
(c) o-nitrophenol
(d) phenol

Answer 1

$\huge\color{red}{AnSWer}$✔✔

In case of $\color{orange}{o-nitrophenol}$ (option c) intramolecular hydrogen bonding is present .

EXtrA InFormation⤵♏

Due to this ,attraction between two molecules is less. Hence boiling point of o-nitrophenol is less.

In case of m-nitrophenol ,intermolecular hydrogen bonding is present .Hence m-nitrophenol boils at elevated temperature.
