Identify the major products A and B respectively in the following reactions of phenol :
Show Hint
The Correct Option is D
Solution and Explanation
Reaction B: phenol with CHCl3/NaOH then H3O+ is the Reimer-Tiemann reaction. The electrophile is dichlorocarbene (:CCl2), which attacks the ortho position of the phenoxide, giving salicylaldehyde (2-hydroxybenzaldehyde) as the major product.
So A = p-bromophenol and B = salicylaldehyde.
Answer: (4) p-bromophenol and salicylaldehyde

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:
