    Least stable oxide of chlorine is

    A) \[C{{l}_{2}}O\]                  

    B)  \[Cl{{O}_{2}}\] 

    C)         \[C{{l}_{2}}{{O}_{7}}\]  

    D)         \[Cl{{O}_{3}}\]

    Correct Answer: A

    Solution :

    Key Idea: The stability of oxides increases with increase in oxidation state of halogen.
    Oxide Oxidation state of halogen
    \[C{{l}_{2}}O\] + 1
    \[Cl{{O}_{2}}\] + 4
    \[Cl{{O}_{3}}\] + 6
    \[C{{l}_{2}}{{O}_{7}}\] + 7
    \[\therefore \] \[C{{l}_{2}}O\]is least stable oxide of chlorine
