How to Name Amides
C=O beside the N
No C=O beside the N
The carbon chain with C=O is five carbons long, so the root of the name is "pentanamide".
Then, we have:
The carbon chain with C=O is four carbons long, and it has a double bond starting with carbon 2 on the chain. The root of the molecule name is but-2-enamide (Notice the "ene" for the double bond)
There are two Cl atoms (chloro groups) on the N This molecule is
Also note, if you know about cis/trans or E/Z, then the real name for this molecule is
