Methods Yielding Only 3 Amines

1. By heating alcoholic solution of NH₃ with excess of alkyl halide -

2. By decomposition of tetra – alkyl ammonium hydroxide

However decomposes in different way.

Illustration 11. Consider the following sequence of reactions

Which of the following is correct?

(A)	B is tertiary amine		(B)	C is
(C)	C is		(D)	None of these

Solution. Hoffmann’s elimination.

Hence (B) is correct.

Illustration 12. Which of the following compounds on hydrolysis yield carboxylic acid and a secondary amine?

(A)

(B)

(C) CH₃CH₂NC (D) CH₃CONHCH₃

Solution: Compound having two alkyl group on N will give 2° amine.

Hence (A) is correct.

Illustration 13. The reactions which does not produce amine are

(A) (B)

(C)

(D)

None of these

Solution: Amide on dehydration give cynide.

Hence (B) is correct.

Illustration 14. Compete the reaction.

(CH₃)₂CHNH₂

Solution:

Illustration 15.
What are A, B and C

Solution: Let ketone be
