Arrange the following.
In decreasing order of basic strength
Advertisements
Solution
Aliphatic amines are more basic than aromatic amines. Therefore CH3CH2NH2 and CH3NH2 are more basic. Among the ethylamine and methylamine. ethylamine was experienced more +I effect than methylamine and hence ethylamine is more basic than methylamine.
Nitro group has a powerful electron-withdrawing group and they have both – R effect as well as – I effect. As a result, all the nitro anilines are weaker bases than aniline. In P-nitro aniline
both – R effect and – I effect of the NO2 group decrease the basicity. Therefore decreasing order of basic strength is,
Ethylamine > Methylamine > Aniline > p-nitro aniline
