Question

Write the correct order of increasing ease of dehydrohalogenation.

\[\ce{\underset{\text{(I)}}{CH3 - CH2 - CH2 - Cl}}\]

\[\ce{\underset{\text{(II)}}{CH3 - CH(Cl) - CH3}}\]

\[\begin{array}{cc}
\ce{CH3}\\
|\\
\ce{CH3-C-Cl}\phantom{...}\\
|\\
\ce{CH3}\\
\ce{(III)}
\end{array}\]

One Line Answer

Solution

The correct order of increasing ease of dehydrohalogenation is, III > II > I.
