WHEN ALIPHATIC PRIMARY AMINE IS HEATED WITH CARBON DISULHIDE AND HGCL2 ALKYL ISOTHIOCYANATE IS FORMED WHICH HAS SMELL LIKE MUSTARD OIL THEREFORE THIS RXN IS CALLED MUSTARD OIL RXN

85
Q

GIVE HEINSBERG RXN FOR PRIMARY SECONDARY TERTIARY

A

THIS METHOD IS CAPABLE TO DIFFERENTIATE PRIMARY SECONDARY TERTIARY AMINES . AMINES ARE HEATED WITH BENZENE SULPHONYL CHLORIDE [HEINSBERG REAGENT] AND VARIOUS PRODUCTS ARE OBTAINED

PRIMARY AMINE = THESE FORM SULPHONAMIDE WHICH ARE SOLUBLE IN KOH

SECONDARY AMINE =SECONDARY AMINE ALSO FORM SULHOAMIDE WHICH ARE INSOLUBLE IN KOH

TERTIARY AMINE= TERTIARY AMINE DOES NOT REACT

86
Q

WHY ANILINE IS LESS BASIC THAN ETHYL AMINE ??

A

ANILNE IS LESS BASIC THAN ETHYL OR CYCLOHEXYL AMINE AS DUE TO RESONACE OF BENXENE NULCEUS THE LONE PAIR OF ELECTRON OF NITROGEN ATOM IS ATTRACTED TOWARDS NLEUS AND GETS DELOACLISED IN THE RING

87
Q

WHY AMINES ARE SOLUBLE IN WATER ??

A

AMINES ARE SOLUBLE IN WATER BECAUSE THEY HAVE HIGHER ELECTRONEGATIVITY ON NITROGEN ATOMS THEY FORM MAXIUM INTERMOLECULAR HYDROGEN BOND WITH WATER MOLECULES HENCE DUE TO DISSOCIATION RXN MOLECULES OF AMINE ARE ATTRACHED WITH WATER MOLECULES THATS WHY AMINES ARE SOLUBLE IN WATER

88
Q

SHORT NOTE ON CARBLYAMINE

A

The carbylamine reaction, also known as Hofmann’s isocyanide test is a chemical test for the detection of primary amines. In this reaction, the analyte is heated with alcoholic potassium hydroxide and chloroform. If a primary amine is present, the isocyanide (carbylamine) is formed which are foul smelling substances.

89
Q

SHORT NOTE ON DIAZOTISATION

A

The chemical process used in converting a primary aromatic amine into the corresponding diazonium salt of the amine

90
Q

SHORT NOTE ON HOFMANN BROMAMIDE RXN

A

When an amide is treated with bromine in an aqueous or ethanolic solution of sodium hydroxide, degradation of amide takes place leading to the formation of primary amine.

91
Q

SHORT NOTE ON COULPING RXN

A

AMILINE REACTS WITH DIAZOIUM CHLORIDE AT ICE COLD TEMP TO GIVE BRIGHT ORANGE RED DYE

92
Q

AMMONOLYICS

A

Ammonolysis is the process of forming amines using, as amminating agents, ammonia or primary and secondary amines.

93
Q

ACETYLATION

A

The acetylation / acylation of amines takes place when the acetyl group substitutes the active hydrogen atom(s) attached to the nitrogen atom of the amine. This can take place by the attack of acetyl chloride on ammines.
