JEE Main 6 April 2023, Shift 1, Chemistry Q73

Question 73 of 90 in this shift, Chemistry question 13 of 30, Section A.

Compound P (M.F. C14H13ON\mathrm{C_{14}H_{13}ON}; M.F. = MOLECULAR FORMULA) on treatment with HCl, Δ\Delta gives a Filter step: Residue Q and Filtrate; the Filtrate with NaOH gives Oily Liquid R. Compound P is neutral, Q gives effervescence with NaHCO3\mathrm{NaHCO_3} while R reacts with Hinsbergs reagent to give solid soluble in NaOH. Compound P is

The figure, in words

Scheme: Compound P (M.F. C14H13ON) --HCl, heat--> Filter -> Residue Q and Filtrate; Filtrate --NaOH--> Oily Liquid R. (M.F. = molecular formula.)
