question_answer 5)

Why do  etc. show acidic characters in aqueous solutions while solutions of compounds like alcohol and glucose do not show acidic character?  

Answer:

and  produce ions in aqueous solution, which is responsible for their acidic character. Alcohol  and glucose  are covalent compounds and they do not undergo dissociation in aqueous solution. This is evident from the fact that their aqueous solutions do not conduct electricity. Hence, the aqueous solutions of alcohol and glucose do not show acidic character even though they contain hydrogen atoms.
