Why do HCl, H2SO4, HNO3 , etc., show acidic character in aqueous solutions while solutions of compounds like C6H12O6 (glucose) and C2H5OH (alcohol) do not show acidic character?

HCl, H2SO4, HNO3 are those which dissociates in aqueous solutions to give H+ ions which determines the acidic property of acids.

Glucose and alcohol does not dissociate in aqueous solution even though they contains hydrogen atoms. This is the reason HCl, H2SO4, HNO3 shows acidic character and glucose and alcohol do not shows acidic character
