A) \[{{[Co{{(en)}_{3}}]}^{3+}}\]
B) \[[Co{{(en)}_{2}}C{{l}_{2}}]Cl\]
C) \[[Co(en){{(N{{H}_{3}})}_{2}}C{{l}_{2}}]Cl\]
D) \[Br>F\]
Correct Answer: A
Solution :
Chlorofluorocarbons (CFCs or freons like \[RC{{H}_{2}}OH\xrightarrow[{}]{}RCHO\]) are responsible for depletion of the ozone layer in the upper strata of atmosphere. They are stable and inert compounds. They absorb UV rays and break down liberating free atomic chlorine which causes depletion of ozone through free radical reaction. \[\overset{\centerdot }{\mathop{Cl}}\,+{{O}_{3}}\xrightarrow{{}}Cl\overset{\centerdot }{\mathop{O}}\,+{{O}_{2}}\] \[Cl\overset{\centerdot }{\mathop{O}}\,+{{O}_{3}}\xrightarrow{{}}\overset{\centerdot }{\mathop{Cl+}}\,2{{O}_{2}}\]You need to login to perform this action.
