Amine

Imagine you're trying to make your morning coffee, but you've run out of milk, so you decide to use cream instead. This situation is similar to the concept of an amine in chemistry, where one or more hydrogen atoms in ammonia are replaced by organic groups, just like how you replaced milk with cream in your coffee. In this analogy, ammonia is your original coffee with milk, the hydrogen atoms are the milk, and the organic groups are the cream; by swapping out the milk for cream, you've created a new version of your coffee, just like how replacing hydrogen atoms with organic groups creates a new compound: an amine.
