Question

In amines 1, 2, 3, 4 carbons can attach to nitrogen, name the type of amine it will be from the order above.

A) Primary, Secondary, Tertiary, Quaternary
B) Secondary, Tertiary, Quaternary, Primary
C) Tertiary, Quaternary, Primary, Secondary
D) Quaternary, Primary, Secondary, Tertiary

Answer 1

Based on the number of carbon atoms attached to nitrogen, the correct sequence of amine types is Primary, Secondary, Tertiary, and Quaternary, with respective 1, 2, 3, 4 carbons attached.

Step-by-step explanation:

Amines are organic compounds characterized by the presence of a nitrogen atom with a lone pair of electrons and can be classified based on the number of carbon atoms attached to that nitrogen atom. Therefore, the types of amines in the order given, that is, when 1, 2, 3, 4 carbons are attached to the nitrogen atom, are as follows:

1. Primary amine: when one carbon is attached to the nitrogen atom.
2. Secondary amine: when two carbons are attached.
3. Tertiary amine: when three carbons are attached.
4. Quaternary ammonium: when four carbons are attached, forming a positively charged ion, but it's not typically referred as 'amine' due to the charged nature.

With this information, the correct answer to the question is A) Primary, Secondary, Tertiary, Quaternary.
