Answer 1

Step-by-step explanation:

The basic chemical structure is that of ammonia (NH3) with the key atom being the central nitrogen atom. Try to remember that an amine is just like ammonia because ammonia is a simple molecule to recall. ... Primary amines are called things like methylamine (CH3-NH2) and ethylamine (CH3-CH2-NH2).
