The correct order of the basis strength of methyl substituted amines in aqueous solution is:
Options
- AC H 3 2 N H > C H 3 N H 2 > C H 3 3 N
- BC H 3 3 N > C H 3 N H 2 > C H 3 2 N H
- CC H 3 3 N > C H 3 2 N H > C H 3 N H 2
- DC H 3 N H 2 > C H 3 2 N H > C H 3 3 N
Correct answer
A. C H 3 2 N H > C H 3 N H 2 > C H 3 3 N
Step-by-step solution
Combined effect of the inductive effect of Alkyl group + I , steric hindrance and the salvation of Amines causes the basicity order to be Secondary Amine > Primary Amine > Tertiary Amine C H 3 2 N H > C H 3 N H 2 > C H 3 3 N
