# Arrange the following in increasing order of their basic strength: C2H5NH2, (C2H5)2NH, (C2H5)3N, C6H5NH2 - CBSE (Science) Class 12 - Chemistry

#### Question

Arrange the following in increasing order of their basic strength:

C2H5NH2, (C2H5)2NH, (C2H5)3N, C6H5NH2

#### Solution

Considering the inductive effect and the steric hindrance of the alkyl groups, C2H5NH2, (CH5)2NH2,and their basic strengths as follows:

C_2H_5NH_2(C_2H_5)_3N<(C_2H_5)_2NH

Again, due to the −R effect of C6H5 group, the electron density on the N atom in C6HNH2 is lower than that on the N atom in C2H5NH2. Therefore, the basicity of C6H5NH2 is lower than that of C2H5NH2. Hence, the given compounds can be arranged in the increasing order of their basic strengths as follows:

C_6H_5NH_2 < C_2H_5NH_2 < (C_2H_5)_3N < (C_2H_5)_2NH

Is there an error in this question or solution?
