Question

You will use a relatively new type of mass spectrometry, ASAP-MS, to verify the molecular weights of your isolated compounds from part 1. You will also carry out melting point determinations of the obtained solids from part 1 both as a way to confirm their identities and to assess their purity. Part 1 was an acid/base extraction with the original mixture being a 1:1:1 mixture of trans-cinnamic acid, ethyl 4-aminobenzoate (benzocaine), and N,N-diethyl-3-toluamide (DEET).

Write a prediction of the number of peaks expected in the C-13 NMR spectrum of all three components of the original mixture.
