Identify the type of reaction when benzene reacts with nitrating mixture.

Options

  1. ASubstitution
  2. BAddition
  3. CElimination
  4. DPolymerization

Correct answer

A. Substitution

Step-by-step solution

Benzene reacts with a nitrating mixture (a mixture of concentrated HNO3HNO_3 and concentrated H2SO4H_2SO_4) to form nitrobenzene.

In this process, the nitrating mixture generates the nitronium ion (NO_2^+),whichactsasanelectrophile.<br><br>Theelectrophileattackstheelectron−richbenzenering,replacingoneofitshydrogenatomswithanitrogroup(), which acts as an electrophile.<br><br>The electrophile attacks the electron-rich benzene ring, replacing one of its hydrogen atoms with a nitro group (-NO_2).<br><br>Sinceahydrogenatomisreplacedbyanothergroup,thisisanelectrophilicaromaticsubstitutionreaction.<br><br>Answer:Substitution).<br><br>Since a hydrogen atom is replaced by another group, this is an electrophilic aromatic substitution reaction.<br><br>Answer: Substitution
