Question.
Why do $\mathrm{HCl}, \mathrm{HNO}_{3}$, etc., show acidic character in aqueous solution while solutions of compounds like alcohol and glucose do not show acidic character?

solution:
$\mathrm{HCl}$ and $\mathrm{HNO}_{3}$ dissociate in the presence of water to form hydrogen or hydronium ions. Although aqueous solutions of glucose and alcohol contain hydrogen, these cannot dissociate in water to form hydrogen or hydronium ions. Hence, they do not show acidic character.
