Question

Write reactions to prepare ethanamine from. (a) acetonitrile (b) nitroethane (c) propuonamide​

Answer 1

Answer:
a) through Mendius reaction
B)nitroethane on reduction in presence of Sn/HCl or LiAlH4 in ether gives ethaneamine .
C)by Hoffman bromamide reaction .

Explanation:

Answer 2

Answer:

Ethanamine can be produced from

• Acetonitrile by Mendius reaction
• Nitroethane by reduction with Sn/HCl or H2 /Ni or LiAlH4
• propanamide by Hoffman Bromamide Reaction

Explanation:

1. Mendius reaction is a reaction that is used to carryout redution of cyanide(CN) group of nitriles to primary amines. Acetonitrile can undergo Mendius reaction to form ethanamine.
2. The Reduction of Nitroethane by Sn/HCl is given in reaction.
3. Hoffman Bromamide reaction is the reaction of amide with Br2/ KOH to form amine. Propanamide is treated with Br2/KOH to form ethyl amine. In place of KOH NaOH can also be used.
