    Oxidation number of carbon in \[C{{H}_{3}}-Cl\]is

    A)  \[-3\]                                   

    B)  \[-2\]

    C)  \[-1\]                                   

    D)  \[0\]

    Correct Answer: B

    Solution :

    \[C{{H}_{3}}-Cl\] Suppose the oxidation number of carbon = x The oxidation number of \[Cl=-1\] The oxidation number of \[H=+1\] \[C{{H}_{3}}Cl\]                                 \[x+3\times 1+(-1)=0\]                                 \[x+3-1=0\]                                 \[x=-2\] So, the oxidation number of carbon is \[=-2\]
