Question

Classify each of the following amines as primary (1°), secondary (2°), or tertiary (3°):

c. Chemical structure of an amine with a benzene ring and an amino group (NH2) attached, indicating a primary amine.

Accepted Answer

Welcome back, everyone determine whether the following compound is classified as a primary, secondary or tertiary. I mean, first of all, let's recall that primary secondary and tertiary amines, they differ by the number of nitrogen carbon bonds. Primary amines, they contain one alky group bonded to nitrogen and nitrogen must have two hydrogens. Now, secondary means, well, we are replacing one hydrogen from the amino group with an additional alkyl group. So now we're going to have two nitrogen carbon bonds. That's why they are called secondary, they have two alkyl groups bonded to nitrogen. And then there is one hydrogen remaining. If we decide to replace the final hydrogen with an additional alky group, we're going to have three nitrogen carbon bonds. And therefore, that would correspond to a tertiary. I mean, so what do we have in this case? Well, essentially, if we locate the nitrogen atom, we can identify one nitrogen carbon bond when we consider the carbon atom on the left. So essentially one alkyl group on the left, another alal group on the right. And now if we go down, there's the third alcal group, so we have a total of three alky groups which corresponds to R one, R two and R three. And therefore, this must be a tertiary. I mean, another another way to identify it as a tertiary, I mean is to simply understand that nitrogen is not bonded to any hydrogen atoms directly, which is a characteristic of a tertiary, I mean, right, we can essentially take a look at the number of hydrogen atoms instead. But by definition, we simply want to count the nitrogen carbon bonds and that will be our final answer. Thank you for watching.
