Vedclass · Answer

(B) From the reaction $(R) \xrightarrow{O_3} P + O$,we know that $(R)$ is an alkene that undergoes ozonolysis to produce $P$ and $O$.From the first reaction,$(P)$ is formed by the aldol condensation of acetone $(CH_3COCH_3)$,which is $CH_3-CO-CH=C(CH_3)_2$ (mesityl oxide).From the second reaction,$(Q)$ is the Cannizzaro reaction of benzaldehyde $(PhCHO)$ to give benzyl alcohol $(Ph-CH_2OH)$ and benzoate ion $(Ph-COO^-)$.Thus,$O$ is benzaldehyde $(PhCHO)$ and $P$ is mesityl oxide $(CH_3-CO-CH=C(CH_3)_2)$.Ozonolysis of an alkene $R$ gives $P$ and $O$. The structure of $R$ is obtained by joining the carbonyl carbons of $P$ and $O$ with a double bond.$R = Ph-CH=C(CH_3)_2$.

The structure of $(R)$ is:
