Phenol on heating with \(\mathrm{CHCl_3}\) and NaOH gives salicylaldehyde. The reaction is called:
Show Hint
- Reimer - Tiemann reaction
- Claisen reaction
- Cannizzaro's reaction
- Hell - Volhard - Zelinsky reaction
The Correct Option is A
Solution and Explanation
Hydrolysis of the \(\mathrm{-CHCl_2}\) group gives \(\mathrm{-CHO}\), forming salicylaldehyde (o-hydroxybenzaldehyde).
This is the Reimer-Tiemann reaction.
Answer: (1) Reimer - Tiemann reaction

Top JEE Main Questions
- Two masses $m$ and $\frac{m}{2}$ are connected at the two ends of a massless rigid rod of length $l$. The rod is suspended by a thin wire of torsional constant $k$ at the centre of mass of the rod-mass system(see figure). Because of torsional constant $k$, the restoring torque is $\tau =k\theta$ for angular displacement $\theta$. If the rod is rota ted by $\theta_0$ and released, the tension in it when it passes through its mean position will be:
