    Which has the maximum percentage of chlorine?

    A)  \[{{C}_{6}}{{H}_{6}}C{{l}_{6}}\]

    B)         \[CHC{{l}_{3}}\]              

    C)         \[{{C}_{6}}{{H}_{5}}Cl\]

    D)         \[C{{H}_{3}}Cl\]

    Correct Answer: B

    Solution :

    \[\text{CHC}{{\text{l}}_{\text{3}}}\]has maximum percentage of chlorine. Molecular weight of \[\text{CHC}{{\text{l}}_{3}}\] \[=12+1+(35.5\,\times \,3)\] \[=119.5\] \[\therefore \] Percentage of chlorine in \[\text{CHC}{{\text{l}}_{\text{3}}}\]                                 \[=\frac{106.5}{119.5}\times 100\] \[=89.12%\]
