    $CH_3Cl$
  • B
    $\begin{matrix}
       ^{Cl}  \\
       _{{{H}_{3}}C}  \\
    \end{matrix}\begin{matrix}
       \text{ }\!\!\backslash\!\!\text{ }  \\
       /  \\
    \end{matrix}C=C\begin{matrix}
       /  \\
       \text{ }\!\!\backslash\!\!\text{ }  \\
    \end{matrix}_{Cl}^{H}$
  • $CH_2Cl_2$
  • D
    $\begin{matrix}
       ^{Cl}  \\
       _{{{H}_{3}}C}  \\
    \end{matrix}\begin{matrix}
       \text{ }\!\!\backslash\!\!\text{ }  \\
