Question

How will you prepare ethyl amine from acetamide ?

Answer 1

Hint: The chemical compound acetamide has the formula $ \text{C}{{\text{H}}_{\text{3}}}\text{CON}{{\text{H}}_{\text{2}}} $ . It's the most basic amide made from acetic acid. It's used as a plasticizer and an industrial solvent in some cases. Acetamide is a chemical intermediate between acetone, which has two methyl ( $ C{{H}_{3}} $ ) groups on either side of the carbonyl ( $ CO $ ), and urea, which has two amide ( $ N{{H}_{2}} $ ) groups.

Complete answer:
The chemical molecule ethylamine, commonly known as ethanamine, has the formula $ \text{C}{{\text{H}}_{\text{3}}}\text{C}{{\text{H}}_{\text{2}}}\text{N}{{\text{H}}_{\text{2}}} $ . The odour of this colourless gas is similar to that of ammonia. It condenses to a liquid miscible with almost all solvents at slightly below room temperature. As is typical of amines, it is a nucleophilic base. In the chemical industry and organic synthesis, ethylamine is frequently used.
LAH stands for lithium aluminium hydride, which is an inorganic substance having the chemical formula $ \text{LiAl}{{\text{H}}_{\text{4}}} $ . It's a solid grey colour. This chemical is employed in organic synthesis as a reducing agent, particularly for the reduction of esters, carboxylic acids, and amides. The solid reacts violently with water, producing gaseous hydrogen ( $ {{\text{H}}_{\text{2}}} $ ). For hydrogen storage, certain similar derivatives have been explored.
Hydrogenation is a chemical process that occurs when molecular hydrogen ( $ {{\text{H}}_{\text{2}}} $ ) reacts with another molecule or element in the presence of a catalyst, such as nickel, palladium, or platinum. Organic molecules are often reduced or saturated using this method. Hydrogenation is the process of adding two hydrogen atoms to a molecule, most often an alkene. The process requires catalysts to be useful; non-catalytic hydrogenation occurs only at extremely high temperatures. Hydrogenation breaks down hydrocarbons' double and triple bonds.
Ethylamine is produced when acetamide is reduced using $ \text{LiAl}{{\text{H}}_{\text{4}}} $ or sodium and alcohol. Acetamide is reduced using sodium and absolute alcohol or $ \text{LiAl}{{\text{H}}_{\text{4}}} $ in ether or hydrogen in the presence of a nickel catalyst to produce ethylamine.
 $ \text{C}{{\text{H}}_{\text{3}}}\text{CON}{{\text{H}}_{\text{2}}}\xrightarrow[\text{Na + }{{\text{C}}_{\text{2}}}{{\text{H}}_{\text{5}}}\text{OH}]{\text{LiAl}{{\text{H}}_{\text{4}}}}\text{C}{{\text{H}}_{\text{3}}}\text{C}{{\text{H}}_{\text{2}}}\text{N}{{\text{H}}_{\text{2}}}\text{+ }{{\text{H}}_{\text{2}}}\text{O} $ .

Note:
Organic reduction reactions are redox processes in which organic molecules are involved. Oxidations and reductions differ from conventional redox reactions in organic chemistry because many processes bear the term but do not require electron transport in the electrochemical sense. Instead, acquisition of oxygen and/or loss of hydrogen are the important criteria for organic oxidation.
