Aromatic Aldehydes Ketones and Acids - Result Question 19

####23. Compound $P$ and $R$ upon ozonolysis produce $Q$ and $S$, respectively. The molecular formula of $Q$ and $S$ is $C _8 H _8 O \cdot Q$ undergoes Cannizzaro reaction but not haloform reaction, whereas $S$ undergoes haloform reaction but not Cannizzaro reaction.

(2017 Adv.) (i) $P \xrightarrow[\text { (ii) } Zn / H _2 O]{\text { (i) } O _3 / CH _2 Cl _2} \underset{\left(C _8 H _8 O\right)}{Q}$ (ii) $R \xrightarrow[\text { (ii) } Zn / H _2 O]{\stackrel{\text { (i) } O _3 / CH _2 Cl _2}{\longrightarrow}} \underset{\left(C _8 H _8 O\right)}{S}$

(a)

(b)

(c) $H _3$
