Question

Which of the following statement is correct?

• A. Bromination of phenol in CS\(_2\), at low temperature gives 2,4,6-tribromophenol.
• B. Oxidation of phenol with chromic acid gives benzene.
• C. Conversion of phenol into tribromophenol by bromine water is a nucleophilic substitution reaction.
• D. p-Nitrophenol is steam volatile due to intermolecular hydrogen bonding.
• E. The intermediate in Reimer-Tiemann reaction is substituted benzal chloride.

Hint:

In Reimer-Tiemann reaction, chloroform is used to introduce a formyl group (-CHO) in the ortho or para position relative to the hydroxyl group of phenol.

Answer 1

Answer: (E)

The Reimer-Tiemann reaction involves the electrophilic substitution of phenol with chloroform to form substituted benzal chloride.
