    In antartica, ozone depletion is due to the formation of the following compound:

    A) Acrolein                        

    B) Peroxyaceltylnitrate

    C) \[S{{O}_{2}}\,and\,S{{O}_{3}}\]                     

    D) Chlorine nitrate

    Correct Answer: D

    Solution :

    [d] Chlorine nitrate Ozone hole has mainly been observed in the stratosphere over Antarctica. Because in other parts of stratosphere, chlorine monoxide radicals combine away with the oxides of nitrogen present in stratosphere and the chlorine free radicals combine away with methane present in stratosphere as follows: \[Cl{{O}^{\bullet }}+N{{O}_{2}}\to \underset{Chlorine\,nitrate}{\mathop{ClON{{O}_{2}}}}\,\] \[C{{l}^{\bullet }}+C{{H}_{4}}\to C{{H}_{3\bullet }}+HCl\] In clouds \[ClON{{O}_{2}}+{{H}_{2}}O\xrightarrow{hydrolysis}HOCl+HN{{O}_{3}}\]
