WebMar 29, 2016 · METHYLAMINE. CH3NH2 contains a methyl group, which is electron-donating. That is, it inductively donates electrons through the N−Br bond towards nitrogen, which "activates" the nitrogen's Lewis base behavior since there is more electron density around it. The more electron density around the nitrogen, the more it has available to … WebThe combined effect of the pushing effect of the alkyl group (+I effect), steric hindrance and the salvation of amines causes the basicity order to be: (basicity of tertiary is almost the same as that of primary).
