Organic: Amines

Question:

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.

What is the suitable temperature to carry out ammonolysis of alkyl halides?
Options:
273K
100K
373K
Zero
Correct Answer:
373K
Explanation:
This process of cleavage of the C–X bond by ammonia molecule is known as ammonolysis. The reaction is carried out in a sealed tube at 373 K.
