Chemical Reactions of Amines
Preparation of Amines Classification of Amines On the basis of the presence of replaceable hydrogen atoms we can classify amines into three types: Primary Amines: The amine is primary amine when an alkyl or Aryl group replaces one of three h ydrogen atoms Secondary Amines: It is a secondary amine when the alkyl or |

What reagents are used to label amines?
- There are three major classes of commonly used reagents to label amines: active esters (which include succinimidyl esters (SE), sulfosuccini midyl esters (SSE), tetrafluorophenyl esters (TFP), and sulfodichlorophenol esters (SDP)), isothiocyanates (ITC), and sulfonyl chlorides (SC).
How do amines react with acids?
- Amines, being basic in nature, react with acids to form salts. Amine salts on treatment with a base like NaOH, regenerate theparent amine. Amine salts are soluble in water but insoluble in organic solventslike ether. This reaction is the basis for the separation of amines fromthe non basic organic compounds insoluble in water.
How do amines undergo alkylation?
- Amines undergo alkylation on reaction with alkyl halides (refer Unit10, Class XII). Aliphatic and aromatic primary and secondary amines react withacid chlorides, anhydrides and esters by nucleophilic substitutionreaction. This reaction is known as acylation. You can considerthis reaction as the replacement of hydrogen atom of –NH or >N–H
What is an example of an amine?
- Amines constitute an important class of organiccompounds derived by replacing one or more hydrogenatoms of ammonia molecule by alkyl/aryl group(s). Innature, they occur among proteins, vitamins, alkaloidsand hormones. Synthetic examples include polymers,dyestuffs and drugs.
