a) what are the two compound present in this dample? draw the structures and label each set of hydrogens as Ha,Hb,Hc etc.

b) assign peaks on the NMR spectrum to each set of hydrogens (chemical shifts and splitting patterns)

c) set one intergration value of the most abundant compund to the appropriate number of hydrogens and determin intergration values for each set of peaks

use the H NMR graph to find what two compouds are present in the mixture. will up vote!
