Question 21.63: Deduce the structure of the following compound based on the ......

The singlet of intensity 5H at 7.1 ppm is due to a phenyl group. The triplet of intensity 3H at 1.2 ppm and the quartet of intensity 2 at 4.1 ppm indicate three protons and two protons, respectively, splitting each other on neighboring carbon atoms; the methylene group is bonded to an oxygen atom. The singlet of intensity 2H indicates a methylene group with no neighboring protons; its position at 3.6 ppm indicates that the protons are bonded to a carbon atom that is also bonded to an oxygen atom or a benzene ring. The compound is ethyl 2-phenylethanoate.
