Hydrogen bonding is maximum in ethanol.
Hydrogen bonding is maximum in ethanol.
Hydrogen bonding is observed when $H$ atom is attached to more electronegative $N , F$ or $O$ atom.
Thus, hydrogen bonding is possible in ethanol and triethylamine.
In ethanol, $H$ is attached to a more electronegative oxygen than in triethylamine, in which $H$ is attached to a less electronegative nitrogen.
Moreover, in triethyl amine, the $+ I$ effect of three methyl groups decreases the extent of hydrogen bonding.
