A) \[C{{H}_{3}}C{{H}_{2}}{{N}^{+}}{{(C{{H}_{3}})}_{3}}{{I}^{-}}\xrightarrow{heat}\] \[C{{H}_{2}}=C{{H}_{2}}+{{(C{{H}_{3}})}_{3}}N+HI\]
B) \[C{{H}_{3}}C{{H}_{2}}{{N}^{+}}{{(C{{H}_{3}})}_{3}}O{{H}^{-}}\xrightarrow{heat}\] \[C{{H}_{2}}=C{{H}_{2}}+{{\left( C{{H}_{3}} \right)}_{3}}N+{{H}_{2}}O\]
C) Both [a] and [b]
D) \[C{{H}_{3}}C{{H}_{2}}N{{H}_{2}}\xrightarrow{heat}\] \[{{\operatorname{CH}}_{2}}=C{{H}_{2}}+N{{H}_{3}}\]
Correct Answer: B
Solution :
[b] This is an example of Hofmann elimination which generally takes place by \[{{E}_{2}}\] mechanism and the latter requires a strong base (recall that \[O{{H}^{-}}\] is a strong base than\[{{I}^{-}}\]). The\[NH_{2}^{-}\], being a strong base, can't be eliminiated easily.
