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 ___3____ C absorptions ___4____
b) 
H absorptions ___4____C absorptions ___5____
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.
a - 1H at 11 ppm, singlet
b - 2H at 2 ppm, quartet
c - 3H at 1 ppm, triplet
a - 1H at 3 ppm, quartet
b - 3H at 1.5 ppm, doublet
c - 9H at 1 ppm, singlet
