    The major products obtained from the following sequence of reactions are: \[\left( C{{H}_{3}} \right) CHC{{H}_{2}}N {{(C{{H}_{2}}C{{H}_{3}})}_{2}}\xrightarrow{C{{H}_{3}}I}\]            \[\xrightarrow[{{H}_{2}}O]{A{{g}_{2}}O}\xrightarrow{heat}products\]

    A) \[{{(C{{H}_{3}})}_{2}}CHC{{H}_{2}}N{{H}_{2}}+{{H}_{2}}C=C{{H}_{2}}\]

    B) \[{{(C{{H}_{3}})}_{2}}NC{{H}_{2}}C{{H}_{3}}+{{H}_{2}}C=C{{\left( C{{H}_{3}} \right)}_{2}}\]

    C) \[{{(C{{H}_{3}})}_{2}}CHC{{H}_{2}}-\overset{\overset{{{\operatorname{CH}}_{3}}}{\mathop{|}}\,}{\mathop{N}}\,-C{{H}_{2}}C{{H}_{3}}+{{H}_{2}}C=C{{H}_{2}}\]

    D) \[a{{(C{{H}_{3}})}_{3}}\overset{+}{\mathop{N}}\,C{{H}_{2}}C{{H}_{3}}{{I}^{-}}+{{H}_{2}}C=C{{H}_{2}}\]
