After helping me to understand this, could you please tell me the specific names for these functional groups:

AMINE: NH2
AMIDE: H-N-C=O

Thank-you

A carbon atom with a -NH2 group attached is an amine. Examples are ethyl amine, methyl amine, etc.
ethyl amine is C2H5NH2.
methyl amine is CH3NH2.

The -C=O with -NH2 attached to the C (in addition to the =O and the -, is an amide.

It may appear to the uninitiated that the amide has an amine group in it but that isn't so. If the -NH2 group is attached to a carbon atom by itself it is an amine. BUT, if the carbon atom to which the NH2 group is attached has a =O on it, the C=O(NH2) group together is a group and that is an amide. Amines are basic. Amides are neutral. I hope this is what you were looking for.
