Solution
\[\begin{array}{cc}
\ce{H3C}\\
\phantom{......}\backslash\\
\phantom{...........}\ce{NH}\\
\phantom{......}/\\
\phantom{}\ce{H3C}\\
\end{array}\]
Explanation:
The greater will be the strength of base, the greater will be its reactivity towards dilute \[\ce{HCl}\]. Hence, \[\ce{(CH3)2NH}\] has the highest basic strength as it has the highest reactivity.
