Spectroscopy Problems 12.67 and 12.68 are intended for students who have already learned about spectroscopy in Chapters A-C. 12.67 Treatment of alcohol A (molecular formula CsH120) with CrO3, H2SO4, and H20 affords B with molecular formula CSH100, which gives an IR absorption at 1718 cm. The 'H NMR spectrum of B contains the following signals: 1.10 (doublet, 6 H), 2.14 (singlet, 3 H), and 2.58 (septet, 1 H) ppm. What are the structures of A and B?
