Question

What integral values would you expect for each of the signals in the proton NMR spectrum of 3-methyl-2-butanone?

The answer is 3:1:6 but I don't understand why

• SOLVED PROBLEM 9.3
What integral values (as whole number ratios) would you expect for each of the signals in the
proton
NMR
spectrum
of 3-methyl-2-butanone?
STRATEGY AND ANSWER: There are three distinct proton environments in 3-methyl-2-butanone:
the methyl at C1, the methine (CH) hydrogen at C3, and the two methyl groups bonded to C3, which are
equivalent. The ratio of these signals, in the order just listed, would be 3 : 1:6.
