Organic bases are the AMINES.
Arrange the different type of amines by increasing basicity.
a. 1° < 2° < 3°
b. 3° < 2° < 1°
c. 1° < 3° < 2°
d. 2° < 3° < 1°
c. 1° < 3° < 2°
Although 3° amine has the most electron donating groups (R group), it has less basicity because of steric strain that can be present between H of R groups.
Thus 2° amines are the most basic followed by 3° amines and 1° amines.
