A solution of acetone [(CH3)2C=O] in ethanol (CH3CH2OH) in the presence of a trace of acid was allowed to stand for several days, and a new compound of molecular formula C7H16O2 was formed. The IR spectrum showed only one major peak in the functional group region around 3000 cm−1, and the 1H NMR spectrum is given here. What is the structure of the product?
Jj.198.
The structure of an ester could either be A or B: CH3 O O CH3 T || -C-OCH3 CH3-C CH3-C-O-C-CH3 CH3 CH3 A B Its ¹H NMR spectrum consists of two peaks at 80.9 and 83.6 (relative areas 3:1). Which compound is it? Describe the spectrum that would be expected if it had been the other ester.
