Draw and/or describe everything that can assumed/known about the below peaks (e.g. "it's a -CH2-, attached to either a C=C or C=O, with a CH neighbor on the other side"); note that each peak should be considered individually and they are not part of the same molecule.
a. 3.4ppm, integral of 3, singlet
b. 9.2ppm, integral of 1, triplet
c. 1.6ppm, integral of 2, sextet (6 peaks)
d. 2.4ppm, integral of 1, septet (7 peaks)
e. 4.1ppm, integral of 1, broad singlet
