Why do HCl, `HNO_(3)`, etc., show acidic characters in aqueous solutions while solutions of compounds like alcohol and glucose do not show acidic character?

Text Solution

Verified by Experts

All the acids that are listed, have replaceable hydrogen atoms which they release in aqueous solutionas `H^(+)` ions. Therefore, they show acidic character. However, both ethyl alcohol `(C_(2)H_(5)OH)` and glucose `(C_(6)H_(12)O_(6))` do not have replaceable hydrogen atoms. They fail to evolve hydrogen gas and do not show any acidic character.
