What is the classification of a reaction where the coordination number of the metal center increases but there is no change in the formal oxidation state of the metal center?

• Insertion Reaction

• Reductive Elimination Reaction

• Substitution Reaction

• Oxidative Addition Reaction

What is the condition required for an oxidative addition reaction to occur?

• The metal center must have no empty orbitals

• The metal center must be d2 or greater

• The metal center must have exactly 18 electrons

• The metal center must be coordinatively saturated

What happens in a reductive elimination reaction?

• Coordination number of the metal decreases

• Both oxidation number and coordination number of the metal increase

• Oxidation number of the metal increases

• Both oxidation number and coordination number of the metal decrease

Which type of reaction involves the addition of new ligands into complexes?

• Substitution Reaction

• Insertion Reaction

• Oxidative Addition Reaction

• Reductive Elimination Reaction

What is the conclusion of the study on CO insertion reaction?

• The inserted CO is one previously coordinated to the metal

• The incoming CO is added trans to the acyl group

• Any Lewis bases cannot bring about CO insertion

What is the effect of the reaction proceeding in an oxidative addition reaction?

• Increase in electron density on the metal

• Decrease in the bond order of the C-O bond

• Decrease in the coordination number of the metal

• Increase in the C-O bond strength
