MCQ
Compounds $P$ and $R$ upon ozonolysis produce $Q$ and $S$, respectively. The molecular formula of $Q$ and $S$ is $C_8 \mathrm{H}_8 \mathrm{O}$. $Q$ undergoes Cannizzaro reaction but not haloform reaction, whereas $\mathrm{S}$ undergoes haloform reaction but not Cannizzaro reaction.
($i$) $P \xrightarrow[\text { ii) } \mathrm{Zn} / \mathrm{H}_2 \mathrm{O}]{\text { i) } \mathrm{O}_3 / \mathrm{CH}_2 \mathrm{Cl}_2} \underset{\left(\mathrm{C}_8 \mathrm{H}_8 \mathrm{O}\right)}{Q}$
($ii$) $R \xrightarrow[\text { ii) } \mathrm{Zn} / \mathrm{H}_2 \mathrm{O}]{\text { i) } \mathrm{O}_3 / \mathrm{CH}_2 \mathrm{Cl}_2} \underset{\left(\mathrm{C}_8 \mathrm{H}_8 \mathrm{O}\right)}{S}$
The option(s) with suitable combination of $P$ and $R$, respectively, is(are)
- A$A,C$
- B$A,D$
- ✓$A,B$
- D$A,C,D$
