Phenol with and gives salicylic acid. The reaction is known as:
Phenol with \( C C l_{4} \) and \( K O H \) gives salicylic acid. The reaction is known as:
- A. Friedel-Craft reaction
- B. Reimer - Tiemann reaction
- C. Rosenmund's reaction
- D. siemlet reaction
Step-by-step solution
The Reimer-Tiemann reaction involves treating phenol with chloroform (CHCl3) and a strong base (like KOH) to introduce a formyl group (-CHO) ortho to the hydroxyl group, yielding salicylaldehyde. In this case, carbon tetrachloride (CCl4) is used instead of chloroform, leading to the formation of salicylic acid via further oxidation. This variation is still referred to as the Reimer-Tiemann reaction.
