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?

Why does an aqueous solution of an acid conduct electricity?

Why do acids not show acidic behaviour in the absence of water?

Why acidic character of HCIO_4 higher than HCIO_3 ?

When do solutions show ideal behaviour? Give two examples of ideal solution.

An optically active amide (A)C_5H_(11)NO on acid hydrolysis gives an acid and NH_3 . When (A) is treated with bromide and alkali a compound is obtained which one treatment with nitrous acid gives an optically active alcohol and nitrogen. The alcohol gives positive iodoform test. What is the structure of A and show the reactions involved.

Show that for dimerisation of benzoic acid in benzene solution, degree of association, = 2(1-i) where I = Van't Hoff factor.
