Vedclass · Answer

(B) The strength of a base is directly proportional to its dissociation constant $(K_b)$.Comparing the given values:$1.6 	imes 10^{-6} > 6.3 	imes 10^{-10} > 3.8 	imes 10^{-10} > 5.6 	imes 10^{-4}$ is incorrect; the correct order of magnitude is $5.6 	imes 10^{-4} > 1.6 	imes 10^{-6} > 6.3 	imes 10^{-10} > 3.8 	imes 10^{-10}$.The smallest value of $K_b$ is $3.8 	imes 10^{-10}$,which corresponds to $C_6H_5NH_2$.Therefore,$C_6H_5NH_2$ is the weakest base.
