1. (2 points) Indicate the number of different absorptions expected in the H-1 NMR and C-13 NMR spectra of the following compounds.
a) 
H absorptions _______ C absorptions _______
b) 
H absorptions _______C absorptions _______
2. (4 points each) Refer to the NMR spectra on the back and identify the structures of the two unknown compounds. For full credit you should correlate each absorption with the hydrogens that give rise to that absorption.
