Phenol treated with chloroform in presence of sodium hydroxide, which further hydrolysed in presence of an acid results

Options

ASalicyclic acid
BBenzene-1,2-diol
CBenzene-1, 3-diol
D2-Hydroxybenzaldehyde

Correct answer

D. 2-Hydroxybenzaldehyde

Step-by-step solution

Chloroform CHCl 3 in the presence of an alkali NaOH undergoes formylation of phenol at the ortho-position. This is also called as the Reimer-Tiemann reaction. Hence, the answer is option D.
