A tertiary amine is
A tertiary amine is
- A) ethylamine
- B) diethylamine
- C) triethylamine
- D) tetraethylarnine
Correct Answer: C) triethylamine
Explanation
The question is asking you to identify the tertiary amine among the given options. A tertiary amine is an amine in which the nitrogen atom is connected to three alkyl or aryl groups. In this question, you have four options to choose from: ethylamine, diethylamine, triethylamine, and tetraethylamine.To determine which one is the tertiary amine, you need to count the number of ethyl groups attached to the nitrogen atom. If there are three ethyl groups, then it is a tertiary amine. If there are two ethyl groups, then it is a secondary amine. If there is only one ethyl group, then it is a primary amine.
Option A, ethylamine, has only one ethyl group attached to the nitrogen atom, which makes it a primary amine. Option B, diethylamine, has two ethyl groups attached to the nitrogen atom, which makes it a secondary amine. Option C, triethylamine, has three ethyl groups attached to the nitrogen atom, which makes it a tertiary amine and the correct answer. Option D, tetraethylamine, has four ethyl groups attached to the nitrogen atom, which makes it a quaternary ammonium salt, not a tertiary amine.
In summary, the correct answer to this question is Option C: triethylamine, as it is the only option that has three ethyl groups attached to the nitrogen atom, making it a tertiary amine
