Question

How will you convert phenol into 2 hydroxybenzaldehyde ?​

Answer 1

Answer:

Answer: Phenol can be converted into salicylaldehyde by Reimer-Tiemann reaction. In this reaction phenol is treated with chloroform and aq. NaOH to form an intermediate,which on hydrolysis followed by acidification gives salicylaldehyde.

Answer 2

The correct question is:

How will you convert phenol into o-hydroxybenzaldehyde ?​

Phenol can be converted to o-hydroxybenzaldehyde by the Riemer Tiemann Reaction.

• When a phenol (C6 H5 OH) reacts with chloroform (CHCl3) in the presence of NaOH (sodium hydroxide) at 333 - 334 K, then an aldehyde group attaches at the ortho position of the benzene ring which forms o-hydroxybenzaldehyde.
• Hydroxybenzaldehyde is also known as Salicylaldehyde.
