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. which of the following statements is correct ?A. The dark blue colour of ozone is due to intense absorption of green light.B. oxides of nitrogen and the halogen can not damage the `O_(3)` later.C. Ozone oxidises dry iodine to `I_(2)O_(9)`D.

1.	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.

Ozone forms oragne coloured `KO_(3)` with potassium hydroxide.
Answer» Correct Answer - D (A) The dark blue colour of ozone is due to intense absorption of red light. (B) Oxides of nitrogen and the halaogen can damage the `O_(3)` layer. (C ) `2l_(2)+9[O_(3)] to l_(4)O_(9)+9O_(2)` (D) `2KOH +5O_(3) to 2KO_(3)+5O_(2)+H_(2)O`

The heavier elements of groups 13 and 14 besides the group oxidation state exhibit another oxidation state which is two units lower than the group oxidation state and the stability of this lower oxidation state increases down the group. This concept which is commonly called inert pair effect has been used to explain many physical and chemical properties of the element of these groups. Element of group 13A. exhibit oxidation state of `+3` onlyB. form `M^(+)` and `M^(3+)` ionsC. exhibit oxidation states of +1 and +3D. form `M^(-)` and `M^(+)` ions
