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
