Ozone is a toxic gas and is a strong oxidising agent even then its presence in the stratosphere is very important. Explain what would happen if ozone from this region is completely removed ?

What would happen if the ozone layer in the atmosphere completely disappears ?

Read source given below and answer the question which follow: "I believe separate electorates will be suicidal to the minorities" During the debate on 27 August 1947, Govind Ballabh Pant said: I believe separate electorates will be suicidal to the minorities and will do them tremendous harm. If they are isolated for ever, they can never convert themselves into a majority and the feeling of frustration will cripple them even from the very beginning. What is it that you desire and what is our ultimate objective? Do the minorities always want to remain as minorities or do they ever expect to form an integral part of a great nation and as such to guide and control its destinies? If they do, can they ever achieve that aspiration and that ideal if they are isolated from the rest of the community? I think it would be extremely dangerous for them if they were segregated from the rest of the community and kept aloof in an airtight compartment where they would have to rely on others even for the What are separate electorates ? What are separate electrons?

Explain the following with proper reason : (i)Fluorine cannot be prepared from fluorides by chemical oxidation. (ii)Anhydrous HCl is a bad conductor of electricity while aqueous HCl is a good conductor. (iii)Halogens are strong oxidising agents. (iv)Bleaching of flowers by chlorine is permanent while after bleaching with SO_(2) , the colour returns. (v)Iodine dissolves more in KI solution than in water. (vi) KHF_(2) is well known whereas KHCI_(2) or KHBr_(2) does not exist. (vii)Ferric iodide is very unstable but ferric chloride is stable. (viii)Fluorine does not form F_(3)^(-) (polyhalide) ion. (ix)HF is not stored in glass bottles but kept in wax lined bottles. (x)HF has a greater electronegativity difference and more ionic character than HCl, HBr and Hl but it is the weakest acid.

Ozone is an unstable, dark blue diamagnetic gas. It absorbs strongly the UV radiation, thus proteching the people on the earth from the harmful UV radiation from the sun. The use of chloroflurocarbon (CFC) in aeroslos and refrigrators, and their subsequent escape into the atomsphere, is blamond for making holes in the ozone layer over the Antarctic, and Arctic. Ozone acts as a strong oxdising agent in acidic and alkaline medium. For this property ozone is used as a germicide and disinfectant for sterillising water and improving the atmosphere of croweded places. Identify the incorrect statement with respect to ozone.
