Question

phenol reacts with aq.br2 at 298k to give?​

Answer 1

Answer:

hry mate !!.. gud morng !!

Explanation:

This leads to the production of two products which are o-bromophenol and p-bromophenol. Explanation: When phenol is reacted with bromine in the presence of a non-polar compound which is (carbon disulfide), it results in the formation of two products. The products are ortho-bromophenol and para-bromophenol

Phenol reacts with bromine in CS2  at low temperature to give o and p-bromophenol.

Phenol produces a white precipitate of 2,4,6-tribromophenolol when combined with excess bromine water. In order to have 2,4,6-tribromophenol, phenol reacts with bromine water. The ionisation is promoted in liquids. To form phenoxide ion, phenol is ionised, which is much stronger for directing ortho-para.

#note

Phenol reacts with bromine water to give 2,4,6-tribromophenol. In water, ionisation is facilitated. Phenol gets ionised to form phenoxide ion, which is even better ortho-para directing. Bromine also gets ionised to a larger extent to form a large number of bromonium ions.
