Vedclass · Answer

(A) The $pK_b$ value is inversely proportional to the basic strength of the amine. Alkyl groups are electron-donating groups ($+I$ effect),which increase the electron density on the nitrogen atom,thereby increasing the basicity and decreasing the $pK_b$ value. Among the given options,$NH_3$ has no alkyl groups attached to the nitrogen atom,making it the least basic. Therefore,$NH_3$ has the highest $pK_b$ value.
