हिन्दीThe CORRECT order of the basic strength of methyl substituted amines in aqueous solution is ____.
Correct answer · Option 4
\( (\text{CH}_3)_2\text{NH} > \text{CH}_3\text{NH}_2 > (\text{CH}_3)_3\text{N} \)
Explanation
In aqueous medium, due to inductive effect, solvation effect and steric hindrance, the basicity order of methylamines is \( 2^\circ > 1^\circ > 3^\circ \), i.e., \( (\text{CH}_3)_2\text{NH} > \text{CH}_3\text{NH}_2 > (\text{CH}_3)_3\text{N} \).
