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 (CH₃CH₂NH₂) we need an Amine or Nitrile with the same number of carbon atoms (2 in this case...

Explain the dipoles on the following covalent bonds: Cl-Cl, H-Cl

A dipole is a result of a seperation of charge between two bonded atoms, when one atom has a slight positive charge and the other a slight negative charge. This is a result of the shared pair of electrons...
