Question

The most reactive amine towards dilute hydrochloric acid is:

पर्याय

• \[\ce{CH3 - NH2}\]

• \[\begin{array}{cc}
  \ce{H3C}\\
  \phantom{......}\backslash\\
  \phantom{...........}\ce{NH}\\
  \phantom{......}/\\
  \phantom{}\ce{H3C}\\
  \end{array}\]

• \[\begin{array}{cc}
  \ce{H3C}\\
  \phantom{......}\backslash\\
  \phantom{.................}\ce{NH - CH3}\phantom{}\\
  \phantom{......}/\\
  \phantom{}\ce{H3C}\\
  \end{array}\]

• 

Answer 1

\[\begin{array}{cc}
\ce{H3C}\\
\phantom{......}\backslash\\
\phantom{...........}\ce{NH}\\
\phantom{......}/\\
\phantom{}\ce{H3C}\\
\end{array}\]

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.
