Vedclass · Answer

(A) The basic strength of amines depends on the availability of the lone pair on the nitrogen atom.$1$. In $CH_3NH_2$,the methyl group $(CH_3)$ is an electron-donating group ($+I$ effect),which increases the electron density on the nitrogen atom,making it more basic.$2$. In $NH_3$,there is no substituent effect.$3$. In $ClNH_2$,the chlorine atom $(Cl)$ is an electron-withdrawing group ($-I$ effect),which decreases the electron density on the nitrogen atom,making it the least basic.Therefore,the increasing order of basic strength is: $ClNH_2 < NH_3 < CH_3NH_2$.

Which set represents the increasing order of basic strength (least basic first)?
