Question 14

An organic compound $P$ with molecular formula $C_9H_{18}O_2$ decolorizes bromine water and also shows positive iodoform test. $P$ on ozonolysis followed by treatment with $H_2O_2$ gives $Q$ and $R$. While compound $Q$ shows positive iodoform test, compound $R$ does not give positive iodoform test. $Q$ and $R$ on oxidation with pyridinium chlorochromate (PCC) followed by heating give $S$ and $T$, respectively. Both $S$ and $T$ show positive iodoform test. Complete copolymerization of 500 moles of $Q$ and 500 moles of $R$ gives one mole of a single acyclic copolymer $U$. [Given, atomic mass: $H = 1$, $C = 12$, $O = 16$]
