CUET Preparation Today
Case: Read the following passage and answer accordingly Amines are prepared mainly by the reduction of nitro compounds. Alkyl or benzyl halide on reaction with an ethanolic solution of ammonia undergoes nucleophilic substitution reaction in which the halogen atom is replaced by an amino group. Amines are prepared from Phthalimide. Treating an amide with bromine in an aqueous or ethanolic solution of sodium hydroxide result in amines. |
| Preperation of amines from Phthalimide is known as; |
Gabriel synthesis Stephen reaction Wurts reaction None of the above |
| Gabriel synthesis |
| Gabriel synthesis is used for the preparation of primary amines. Phthalimide on treatment with ethanolic potassium hydroxide forms potassium salt of phthalimide which on heating with alkyl halide followed by alkaline hydrolysis produces the corresponding primary amine. |
