Amides
The AMIDE family has an -NH2 AND a =O on the same end carbon.
The names end in amide.
Yeah, that simple!
There are three carbons, hence propan.
The -NH2 and =O is present.
These compounds are called amides.
This group can only be at the end of a chain, hence no number is required.
A bromine is at carbon 3.
Hence the name is:
3-bromopropanamide
