Answer:
When phenol is treated with chloroform in presence of NaOH at 343 K, salicyaldehyde is formed
(ii) Kolbe's reaction. ... Butan-1-ol is primary alcohol thus no reaction occur.
Phenols on treatment with chloroform in the presence of KOH, a –CHO group is introduced at the ortho position of the benzene ring.
The substituted benzal chloride formed as intermediate on hydrolysis with alkali produces salicylaldehyde. This reaction is known as the Reimer-Tiemann Reaction.
it is also considerd to be an electrophillic attack on benzene .
