Compound P $\displaystyle \left(\mathrm{C}_8 \mathrm{H}_8 \mathrm{O}\right)$ gives a red orange precipitate with $\displaystyle 2,4$-DNP reagent and it does not reduce Fehling's reagent. On drastic oxidation with chromic acid, P gives an aromatic product Q that produces effervescence on treating with aq. $\displaystyle \mathrm{NaHCO}_3$. Compounds P and Q, respectively, are :
