give the order of basic nature of ehanamine ammonia aniline
Bushra, the order of basicity or basic nature for the given set of compounds is as follows:-
Aniline < Ammonia < Ethanamine
The basis for this order is the fact that basicity depends on the ability of a compound to donate a pair of electrons or the ability to abstract a proton. The tendency to donate a pair of electrons increases in ethanamine from that of ammonia due to presence of electron releasing CH3CH2 group which is electron releasing due to +I- Effect (Inductive effect), whereas the tendency to donate a pair of electrons decreases in case of Aniline due to electron withdrawing Phenyl group which withdraws the electron density away from Nitrogen of -NH2 group through mostly the Resonance effect which withdraws the electron density away from Nitrogen and hence the lone pair of electron on N is less available for donation. In case of Ammonia, there is no Inductive or Resonance effect, so its basic nature remains in between that of Ethanamine and Aniline.
Hope this solves your query.
