Arrange the following in decreasing order of their $\mathbf{p K} \mathbf{K}_{\mathbf{b}}$ values
1 d $>$ a $>$ c $>$ b
2 a $>$ b $>$ d $>$ c
3 d $>$ c $>$ b $>$ a
4 a $>$ c $>$ d $>$ b
Explanation:
$\mathrm{pK}_{\mathrm{b}}$ is defined for base which donates lone pair is called Base. For strong base $\rightarrow$ easily give lone pair and high electron density For strong base $\rightarrow$ value of $K_{b}$ is high. $\mathrm{pK}_{\mathrm{b}}=-\log \mathrm{K}_{\mathrm{b}}$ $\downarrow \mathrm{pK}_{\mathrm{b}}=\log \frac{1}{\mathrm{~K}_{\mathrm{b}} \uparrow}$ For the compounds having greater value of $\mathrm{K}_{\mathrm{b}}$ have lesser $\mathrm{pK}_{\mathrm{b}}$ Hence, correct order is (d) $>$ (c) $>$ (b) $>$ (a)

Identify the ortho and para directing groups towards aromatic electrophilic substitution reactions from the following list
1 I, IV, V
2 II, III, VI
3 I, II, IV
4 IV, V, VI
Explanation:
When electron donating group attach with the benzene ring then the group activate the ortho and para position the electron donating group increases the electron density on ortho and para position that's why aromatic electrophilic substitution reaction take place. Here, $-\mathrm{OH},-\mathrm{OCH}_{3}-\mathrm{NHCOCH}_{3}$ are electron donating group which increases the electron density on ortho and para position.
