Q. The increasing order of $p K_{b}$ values of the following compounds is -

$I < II < I V < III$

$II < I V < III < I$

$II < I < III < I V$

$I < II < III < I V$

Basic strength $α K_{b} α \frac{1}{p K _{b}}$

B.S. $α + M, + H, + I α \frac{1}{- M , - H , - I}$

B.S. order $\Rightarrow I > II > I V > III$

$p K_{b}$ order $\Rightarrow III > I V > II > I$

Q. The increasing order of pKb​ values of the following compounds is -

I<II<IV<III

II<IV<III<I

II<I<III<IV

I<II<III<IV
