MCQ
In the following compounds, the decreasing order of basic strength will be:
- A(C2H5)2NH > C2H5NH2 > NH3
- B(C2H5)2NH > NH3 > C2H5NH2
- CNH3 > C2H5NH2 > (C2H5)2NH
- DC2H5NH2 > NH3 > (C2H5)2NH
✓
Answer
- (C2H5)2NH > C2H5NH2 > NH3
Explanation:
(C2H5)2NH > C2H5NH2 > NH3
Basic strength order
(CH3CH2)2NH > CH3CH2NH2 > NH3
2° amine, 1° amine
Alkyl group shows +I effect, and hence increases basicity.
