Q. Which of the following amines is the most basic? (2023) 2023
A.
Methylamine
B.
Aniline
C.
Ethylamine
D.
Dimethylamine
Solution
Dimethylamine is the most basic due to the electron-donating effect of the two methyl groups, which increases the availability of the lone pair on nitrogen.

FAQs
Question: What are the different types of amines? Answer: Amines are classified into three types: primary (1°), secondary (2°), and tertiary (3°) amines, based on the number of carbon atoms attached to the nitrogen atom.
Question: How do I determine the basicity of an amine? Answer: The basicity of an amine is influenced by factors such as the presence of electron-donating or withdrawing groups and the steric hindrance around the nitrogen atom.
