Aminoethane can be prepared by a reduction reaction. Identify a starting compound that can be used to prepare aminoethane by reduction, give the necessary reagent and write an equation for the reaction.

Amines can be prepared by reduction of Amides or Nitriles. To give Aminoethane (CH 3 CH 2 NH 2 ) we need an Amine or Nitrile with the same number of carbon atoms (2 in this case). This would be Acetamide (CH...
