Question
Paragraph I: An organic compound \( P \) with molecular formula \( C _5 H _ 18 O _2\) decolorizes bromine water and also shows positive iodoform test. \( P \) on ozonolysis followed by treatment with \( H _2 O _2\) 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: \( H =1, C =12, O =16\)] Question: The molecular weight of U is
