Question

The most reactive amine towards dilute hydrochloric acid is:

पर्याय

• CH₃ – NH₂

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

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

• 

Answer 1

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

Explanation:

The greater the strength of a base, the greater will be its reactivity towards dilute HCl. Hence, (CH₃)₂NH has the highest basic strength as it has the highest reactivity.
