Question
How many peaks do you expect to see in a 1H NMR of acetanilide? You may assume aromatic protons (protons attached to benzene rings) will give a single, overlapping peak.
Solution
Acetanilide has the following structure:
O=C(NH2)-C6H5
This structure can be broken down into three types of protons (hydrogens):
-
The aromatic protons (protons attached to benzene rings): These are the 5 protons on the benzene ring. As stated in the question, we can assume these will give a single, overlapping peak.
-
The amide protons: This is the 2 protons on the NH2 group. These will give a separate peak.
-
The methine proton: This is the single proton on the carbon adjacent to the carbonyl group. This will give another separate peak.
So, in total, we would expect to see 3 peaks in a 1H NMR of acetanilide.
