Phenol treated with chloroform in presence of sodium hydroxide, which further hydrolysed in presence of an acid results
Updated On: Nov 15, 2024
- Salicyclic acid
- Benzene-1,2-diol
- Benzene-1, 3-diol
- 2-Hydroxybenzaldehyde

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The reaction of phenol with chloroform in the presence of sodium hydroxide, followed by hydrolysis in an acidic medium, is known as the Reimer-Tiemann reaction. This reaction results in the formation of 2-hydroxybenzaldehyde (commonly known as salicylaldehyde). The reaction can be represented as:
\(\text{Phenol} + \text{CHCl}_3 + \text{NaOH} \rightarrow 2\text{-Hydroxybenzaldehyde (salicylaldehyde)}\)
The reaction involves the introduction of a formyl group (-CHO) at the ortho position relative to the hydroxyl group (-OH), producing 2-hydroxybenzaldehyde.
The Correct Answer is: 2-Hydroxybenzaldehyde
