Compound A (C11H16O) has a band in the IR spectrum at 3450 cm-1 (strong, broad) and does not react with pyridinium chlorochromate (PCC) in CH2CI2. Compound A does react with HBr to give compound B (11H15Br). Compound B reacts with potassium f-butoxide to give compound C (C11H14). Ozonolysis of C followed by treatment with Zn and water gives CH3CHO and compound D (C9H10O). The proton NMR spectrum of compound D is given below. Treatment of compound D with ethyl magnesium...
