[PDF] acid hydrolysis in octahedral complexes

  • What is acid hydrolysis in octahedral complexes?

    Acid hydrolysis or aquation reactions may be defined as the reactions in which an aquo complex is formed due to the replacement of a ligand by water molecule. As reaction media is the water itself, H2O concentration (55.5 M) remains almost constant and the change in water concentration cannot be detected at all.

  • What is acid hydrolysis reaction of complexes?

    Acid hydrolysis is a hydrolysis mechanism in organic chemistry in which protic acid is used to catalyse the cleavage of a chemical bond by means of a nucleophilic replacement reaction with the addition of water elements (H2O).

  • What is the mechanism of base hydrolysis of octahedral complex is known as?

    Two types of mechanisms are followed for base hydrolysis in octahedral complexes. (i) SN2 or Associative mechanism. (ii) SN1CB or Dissociation mechanism.
  • Octahedral complexes react either by SN1 or SN2 mechanism in which the intermediates are five and seven-coordinated species, respectively. In both cases, the symmetry of the complex is lowered down and due to this change in crystal field symmetry, the crystal field stabilization (CFSE) value also changes.
