Perchloric Acid

Explain the following: (a) More metal fluorides are ionic in nature than metal chlorides. (b) Perchloric acid is a stronger acid than sulphuric acid. (c ) Fluorine does not undergo disproportionation reactions but other halogens do.

Give appropriate reasons for each of the following : (a)Addition of Cl_2 to Kl solution gives a brown colour but excess of Cl_2 turns it colourless (b)Perchloric acid is a stronger acid than sulphuric acid. ( c)HI can not be prepared by heating Nal with concentrated H_2SO_4

Assign appropriate reasons for each of the following statements. (i)More metal fluorides are ionic in nature than metal chlorides. (ii) Hydrogen fluoride is a weaker acid than hydrogen chloride in aqueous solution. (iii)In aqueous solution HI is a stronger acid than HCI ? (iv) Addition of Cl_(2) to KI solution gives it a brown colour but excess of Cl_(2) turns it colourless. (v) Perchloric acid is a stronger acid than sulphuric acid.

A white 'A' on heating decomposes to produce two products 'B' and 'C'. 'B' on reaction with white phosphorous produces 'D', which is a strong dehydrating agent. 'D' on reaction with perchloric acid converts it to its anhydride. The number of moles of H_(2)O needed to hydrolyse (complete) 1 mole of D is:
