Solution
Pentanamide (C5H11NO) is a linear molecule with an amide functional group at one end.
There are three different types of carbon environments in this molecule:
- The carbon atom in the carbonyl group (C=O) of the amide.
- The carbon atom attached to the nitrogen atom in the amide group.
- The carbon atoms in the remaining part of the alkyl chain. These are all in the same environment because they are all attached to two other carbons (except for the terminal carbon, but it is equivalent to the carbon attached to the nitrogen because they are both attached to one other carbon and two hydrogens).
So, there are 3 different 13C (carbon-13) chemical environments in pentanamide.
