Question
Which of the following is most basic?
Correct Answer
Option C is the correct answer.
Detailed Explanation
In the gas phase or nonpolar solvents, the basicity order is: (CH3)2NH > CH3NH2 > (CH3)3N > NH3. In aqueous solution, dimethylamine is the most basic due to a balance of inductive effects and solvation. Methyl groups are electron-donating, increasing basicity, but steric hindrance and solvation affect higher alkylamines.
Hint
Which amine has the best balance of inductive effect and solvation?
