Question

The correct decreasing order of $pK_b$ is

I > II > III > IV

III > IV > II > I

II > III > IV > I

IV > II > I > III

Answer

IV > II > I > III

Explanation

Solution

Substituent with strong $+$ R effect, $+I$ effect and weaker $-I$ effect increases the basicity. Hence $PK_{b}$ decreases. Also, alkylamines are stronger bases than arylamines. So, the order is (d).
