Arrange the following In decreasing order of `p K_b` values
(I) `C_2H_5 NH_2`
(II) `PhNHMe`
(III) `(C_2H_5)_2 NH`
(IV) `PhNH_2`

Text Solution

AI Generated Solution

To arrange the compounds in decreasing order of pK_b values, we need to analyze the basicity of each compound based on the stability of the lone pair on the nitrogen atom. The lower the basicity, the higher the pK_b value, and vice versa. ### Step-by-Step Solution: 1. **Identify the Compounds**: - (I) Ethylamine: \( C_2H_5NH_2 \) - (II) N-phenylmethylamine: \( PhNHMe \) - (III) Diethylamine: \( (C_2H_5)_2NH \) ...
