Vedclass · Answer

(A) The basic strength of amines depends on the electron-donating inductive effect of the alkyl group $(R)$.As the number of alkyl groups increases,the electron density on the nitrogen atom increases,making the amine more basic.Therefore,the order of basic strength is $NH_3 Since $pK_b = -\log(K_b)$,a higher basic strength corresponds to a lower $pK_b$ value.Thus,the decreasing order of $pK_b$ values is $NH_3 > RNH_2 > R_2NH$.

Identify the correct decreasing order of $pK_b$ values of the following compounds.
