CUET Preparation Today
Which of the following methods of preparation of amines will not give same number of carbon atoms in the chain of amines as in the reactant? |
Reaction of alkyl nitrile with LiAlH4 Reaction of amide with LiAlH4 followed by treatment with water. Heating alkyl halide with potassium salt of phthalimide followed by hydrolysis. Treatment of amide with bromine in aqueous solution of sodium hydroxide |
Treatment of amide with bromine in aqueous solution of sodium hydroxide |
The correct answer is option 4. Treatment of amide with bromine in aqueous solution of sodium hydroxide. Only treatment of amide with Br2 in aqueous solution of NaOH will give an amine with lesser number of carbon atoms than in the reactant while
all the remaining reactions give an amine with the same number of carbon atoms as in the reactant.
