    \phantom{..................}\ce{+}\\
    \ce{CH3 - CH2 - CH - CH2}\\
    \phantom{.....}|\\
    \phantom{.......}\ce{CH3}
    \end{array}$
  • $\begin{array}{cc}
    \ce{+}\phantom{.......}\\
    \ce{CH3 - C - CH2 - CH3}\\
    |\phantom{.......}\\
    \ce{CH3}\phantom{.....}
    \end{array}$
  • C
    $\begin{array}{cc}
    \phantom{.......}\ce{+}\\
    \ce{CH3 - CH2 - C - CH3}\\
    \phantom{.......}|\\
    \phantom{.......}\ce{H}
    \end{array}$
  • D
    $\begin{array}{cc}
    \phantom{...}\ce{CH3}\\
    \phantom{......}|\phantom{...}+\phantom{}\\
    \ce{CH3 - C - CH2}\\
    |\\
    \phantom{..}\ce{CH3}
