The reaction of benzene with bromine gives?

Correct answer: C. Bromo-phenol

  • A. Alkyl bromide
  • B. Hydrogen bromide
  • C. Bromo-phenol
  • D. Bromo cyclohexane

Explanation

The reaction of benzene with bromine in the presence of a Lewis acid catalyst, such as FeBr_3 , results in electrophilic aromatic substitution. The bromine molecule is polarized by the Lewis acid, forming a bromonium ion (Br<sup>+</sup>) which acts as the electrophile. The bromonium ion attacks the benzene ring, leading to the formation of bromobenzene. However, the reaction doesn't stop there.In the presence of a strong base, like NaOH, bromobenzene undergoes further reaction to form bromo-phenol. This reaction involves the nucleophilic attack of hydroxide ion (OH<sup>-</sup>) on the bromobenzene, leading to the formation of bromo-phenol.

About Chemistry of Hydrocarbons

Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
