JEE Main Chemistry question

Phenol reacts with CHCl₃/NaOH (Reimer–Tiemann) to give X, which on treatment with concentrated NaOH (Δ) gives Z. Z is

(A)A mixture of 2-hydroxybenzyl alcohol (salicyl alcohol) and sodium 2-hydroxybenzoate (sodium salicylate)Correct
(B)Pure salicylaldehyde only (no further reaction)
(C)A mixture of 2,6-dichlorophenol and phenol
(D)Sodium benzoate and phenol

Answer: (A)

Solution

The Reimer–Tiemann reaction installs –CHO *ortho* to the –OH, giving salicylaldehyde (X, as its sodium phenoxide salt). Since this aromatic aldehyde has no α-hydrogen, treatment with
