The strongest base amongst the following is (In aqueous state):
Options
- AN H 3
- BC 2 H 5 N H 2
- CC 2 H 5 2 N
- DC 2 H 5 3 N
Correct answer
C. C 2 H 5 2 N
Step-by-step solution
The basic order depends upon the following three factors: 1 . + I effect, basicity increases 2 . steric factor - When R group around N increases, then its ability to accept proton decreases. 3 . Solvation of ammonium ion - When R group around N increases, then its solvation in water is less. In aqueous state, 2 o C 2 H 5 2 N is most stable
