during the reaction of nickel metal reaction‚ nickel metals tend to form an ion with a charge of 2+. This helps it to form complexes because of the empty orbitals it has around it. This nature of the metals allows it to bond with compounds through lone pairs‚ which is scientifically known as the dative bonding. On the second part of this experiment we react the Schiff base ligand with hydrated nickel complex‚ this will allow us to form new nickel complex which is known as. We do this through condensation

attracted by electrophile (electron deficiency atoms or ions ). Ligands are species that have at least one lone pair of electrons that are readily donated to a metal or an ion to form a coordinate bond. According to lewis acid- base theory‚ all ligands are lewis base as they act as donor. In the contrary‚ the metal‚ central atom act as an lewis acid as it receives lone pair electrons from the ligands when forming the complex ions. The properties of lewis acid is to have high electron deficiency
