Question

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 ch2cl2. compound a does react with hbr to give compound b (c11h15br). compound b reacts with potassium t-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 bromide yields
