Question

Phenol reacts with bromine in carbon disulphide solution at low temperature to give as a major product
a) m – Bromophenol
b) o – and p – Bromophenol
c) p – Bromophenol
d) 2, 4, 6, - Tribromo phenol​

Answer 1

Answer:

b

Explanation:

Reaction can be limited to monohalogenation if halogenation is carried out in non polar solvant like CS2, CCl4 or in a solvent of low polarity such as CHCl3 at a low temperature

In nonpolar solvents or solvents of low polarity phenol does not ionize to yield phenoxide ion. Therefore, electophile Br+ has no option but to attack the less active benzene ring of phenol.

Answer 2

Answer:

The answer is a p– Bromophenol
