An organic compound A gives positive Liebermann reaction and on treatment with CHCl₃/KOH followed by hydrolysis gives (B) and (C). Compound (B) gives colour with schiffs reagent but not (C), which is steam volatile. (C) on treatment with LiAlH₄ gives D, C₇ H₈ O₂ which on oxidation gives E. Compound E reacts with (CH₃CO)₂O/CH₃COOH to give a pain relléver F. Give structures of A to F with proper reasoning?

Explanation

Organic compound A is phenol. When treated with `CHCl_3 / KOH` followed by hydrolysis under-going Reimer - Tiemann reaction giving (B) and (`C`)
FIGURE
(`C`) does not give colour with schiff.s base due to intramolecular H bonding and is also steam volatile
