MCQ
Aniline on treatment with conc. $HN{O_3} + $ conc. ${H_2}S{O_4}$ mixture yields
  • A
    $o- $and $p-$nitroanilines
  • B
    $m-$nitroanilines
  • A black tarry matter
  • D
    No reaction

Answer

Correct option: C.
A black tarry matter
c
(c) Nitration of aniline without protecting the amino group is not possible because $HN{O_3}$ is a strong oxidising agent which oxidises aniline.

what rate law best agrees with this mechanism

A reaction takes place in three steps with individual rate constant and activation energy as follows 

     Rate constant     Activation energy
 Step $1$        $k_1$ $E_{a1} = 180\ kJ/mol$
 Step $2$        $k_2$ $E_{a2} = 80\ kJ/mol$
 Step $3$        $k_3$ $E_{a3} = 50\ kJ/mol$

If overall rate constant, $k = {\left( {\frac{{{k_1}{k_2}}}{{{k_3}}}} \right)^{2/3}}$  ,then overall activation energy of the reaction will be  .......... $ kJ/mol$
