Answer to Question 8

Both of these compounds contain two different kinds of protons. In addition, both of the protons in each compound are expected to appear as singlets. However, the position of the absorptions should be diagnostic.
The carboxylic acid proton in acetic acid should appear between 11 and 12  while the methyl singlet should appear between 2 and 3 , as in the bottom spectrum.
