Show Solution

The Correct Option is B

Solution and Explanation

Step 1: Reagent Identification.
The reaction utilizes chloroform (CHCl₃) and sodium hydroxide (NaOH) under heating (Δ), characteristic of the Reimer-Tiemann reaction. This process is employed to synthesize ortho and para-hydroxy compounds by introducing a hydroxyl group (-OH) to the ortho or para position relative to an existing substituent, typically a methyl or halogen group.

Step 2: Reaction Mechanism.
- The initial compound contains a methyl group, and the hydroxyl group is introduced onto the aromatic ring through electrophilic substitution.
- The dominant product will feature the hydroxyl group positioned para to the methyl group, yielding a para-hydroxy methyl derivative.

Step 3: Determination of Product.
The primary product formed is the para-hydroxy methyl compound, which aligns with option (2).

Final Determination: \[\boxed{\text{(2)}}\]
