Question
Explain basic nature of amines.
Solution
Nitrogen atom of amines contains a lone pair of electrons which can be donated. Thus, amines act as Lewis bases. Amines are Lowry-Bronsted bases as they accept a proton. Thus, amines act as bases and nucleophiles.
eg.
a. The reaction of ethylamine with dilute hydrochloric acid results in the formation
of ethyl ammonium chloride.
`CH_3-CH_2-NH_2+HCl⇌CH_3-CH_2NH_3^+Cl^-`
Ethylamine Ethyl ammonium
(Ethanamine) chloride
b. The reaction of aniline with dilute hydrochloric acid results in the formation of
