Question

Consider the reaction

\[\begin{bmatrix}\begin{array}{cc}
\phantom{.......}\ce{CH3}\\
\phantom{....}|\\
\ce{CH3CH2CH2 - \overset{⊕}{N} - CH2CH3}\\
\phantom{....}|\\
\phantom{.......}\ce{CH3}
\end{array}\end{bmatrix}\]\[\ce{OH^- ->[Heat] ?}\]

Which of the following is formed in a major amount?

विकल्प

• \[\ce{CH2 = CH2}\]

• \[\ce{CH3CH = CH2}\]

• Both (1) and (2) in equal amount

• None, as no reaction takes place

Answer 1

\[\ce{CH2 = CH2}\]

Explanation:

\[\begin{bmatrix}\begin{array}{cc}
\phantom{.......}\ce{CH3}\\
\phantom{....}|\\
\ce{CH3CH2CH2 - \overset{⊕}{N} - CH2CH3}\\
\phantom{....}|\\
\phantom{.......}\ce{CH3}
\end{array}\end{bmatrix}\]\[\ce{OH^- ->[Heat] \underline{\text{CH}_2 = \text{CH}_2}}\]
