Vedclass · Answer

(D) The basic strength of amines depends on the availability of the lone pair of electrons on the nitrogen atom.In the given compounds,the lone pair on the nitrogen atom is involved in resonance with the benzene ring.Compound $(I)$ is aniline $(C_6H_5NH_2)$.Compound $(II)$ is $N$-methylaniline $(C_6H_5NHCH_3)$.Compound $(III)$ is $N,N$-dimethylaniline $(C_6H_5N(CH_3)_2)$.The methyl group $(-CH_3)$ is an electron-donating group ($+I$ effect). As the number of methyl groups attached to the nitrogen increases,the electron density on the nitrogen atom increases,making the lone pair more available for donation.Therefore,the basic strength increases as the number of methyl groups increases: $(III) > (II) > (I)$.

Which of the following is the correct order for basic strength?
