   Expected Product: 1 H NMR: The ratio of protons is 2:3:3. Solution. Yes, ethyl acetate was synthesized. First, the ratio of protons equals the number of protons in our expected product. The peak at 1.20 ppm is a triplet that integrates to 3 protons. The integration indicates that the peak corresponds to a methyl group.

   14. Dez. 2023 · Let’s see how it works on the NMR spectra od chloroethane and 2-bromopropae: The height of each integral is proportional to the area of the given signal and the area is determined based in the number of absorbing protons. The integral of signal b is 1.5 times taller than the one for signal a since the proton ratio is 3 : 2.
