How will you prepare ozone by laboratory method? Explain the structure of ozone. |
|
Answer» Solution :In the laboratory ozone is prepared by passing electrical discharge through oxygen. At a potential of 20,000 V about `10%` of oxygen os converted into ozone it GIVES a mixture known as ozonised oxygen. Pure ozone is obtained as a PALE BLUE gas by the fractional distillation of liquefied ozonised oxygen. `UNDERSET("(oxygen)")(O_(2))hArr underset("(atomic oxygen)")(2(O))` `O_(2)+(O)hArr underset("(ozone)")(O_(3))`  Structure of ozone : The ozone molecule have a bent shape and symmetrical with delocalised bonding between the oxygen atoms. |
