Identify the product obtained when phenol reacts with bromine in presence of CS ₂
Options
- AP-Bromophenol
- BMixture of O-Bromophenol and P-Bromophenol
- C2, 4, 6-tribromophenol
- Dm-Bromophenol
Correct answer
B. Mixture of O-Bromophenol and P-Bromophenol
Step-by-step solution
Phenol reacts with bromine in the presence of a non-polar solvent such as CS ₂ or CHCl ₃ at low temperature to undergo electrophilic aromatic substitution. In a non-polar solvent, the ionization of phenol is suppressed, and the electrophile Br ^+ is generated in a smaller concentration compared to the reaction in a polar solvent like water. This prevents polyhalogenation. As a result, mono-bromination takes place, yielding a mixture of ortho-bromophenol (minor product) and para-bromophenol (major product). Therefor
