Quiz-1 Chemistry Coordinate Compounds

What is the difference between structural isomerism and stereoisomerism?

• The difference between structural isomerism and stereoisomerism lies in the arrangement of atoms in the molecules.

• Structural isomerism is only observed in inorganic compounds, while stereoisomerism is only observed in organic compounds.

• Structural isomerism results in molecules with the same physical and chemical properties, while stereoisomerism results in molecules with different properties.

• Structural isomerism involves different functional groups, while stereoisomerism involves different bond types.

Explain the concept of coordination compounds and provide an example.

• Coordination compounds involve the bonding of two metals together, such as Cu and Zn in [CuZn]SO4.

• An example of a coordination compound is [Fe(NH3)6]Cl3, where iron (Fe) is the central metal atom coordinated with six ammonia (NH3) ligands.

• An example of a coordination compound is [Co(NH3)6]Cl3, where cobalt (Co) is the central metal atom coordinated with six ammonia (NH3) ligands.

• In coordination compounds, ligands are always negatively charged ions.

How do metal carbonyls differ from other metal complexes?

• Metal carbonyls contain carbon monoxide ligands bonded to the metal center.

• Metal carbonyls are less reactive than other metal complexes.

• Metal carbonyls do not contain any metal atoms.

• Metal carbonyls have a different color than other metal complexes.

Discuss the role of metal complexes in biological systems.

• Metal complexes in biological systems have no impact on biochemical reactions.

• Metal complexes in biological systems are only found in non-living organisms.

• Metal complexes in biological systems are solely responsible for energy production.

• Metal complexes in biological systems serve functions like oxygen transport, electron transfer, and catalysis, enhancing the efficiency and specificity of biochemical reactions.

What are chelating agents and how do they affect metal ions?

• Chelating agents are compounds that repel metal ions, causing them to disperse in solution.

• Chelating agents are compounds that destabilize metal ions, leading to their precipitation.

• Chelating agents are compounds that accelerate the reaction of metal ions with other substances.

• Chelating agents are compounds that can form multiple bonds with a metal ion, surrounding and capturing the ion. This process is known as chelation. Chelating agents can affect metal ions by forming stable complexes, preventing the metal ions from reacting with other substances or undergoing precipitation.

Explain the concept of catalysis and provide an example of a catalytic reaction.

• Catalysis involves the conversion of a catalyst into a product during the reaction

• The addition of a catalyst to a reaction slows down the rate of the reaction

• An example of a catalytic reaction is the combustion of methane without any catalyst

• An example of a catalytic reaction is the decomposition of hydrogen peroxide into water and oxygen, which is catalyzed by the enzyme catalase.

How does ligand substitution occur in metal complexes?

• Ligand substitution in metal complexes occurs through oxidation-reduction reactions.

• Ligand substitution in metal complexes is a reversible process.

• Ligand substitution in metal complexes is solely dependent on the size of the metal ion.

• Ligand substitution in metal complexes can occur through associative or dissociative pathways.

What is the significance of isomerism in complex compounds?

• Isomerism in complex compounds has no effect on their properties

• Isomerism in complex compounds allows for different spatial arrangements of atoms within the same molecular formula, leading to different physical and chemical properties.

• Isomerism in complex compounds only occurs in simple molecules

• Isomerism in complex compounds always results in identical physical and chemical properties

Discuss the importance of coordination compounds in industrial processes.

• Coordination compounds are important in industrial processes for catalysis, stabilization of intermediates, and improving reaction efficiency.

• Coordination compounds have no relevance in industrial processes

• Coordination compounds are only used in theoretical chemistry, not in practical applications

• Coordination compounds are harmful to industrial processes and should be avoided

What are the different types of isomerism found in coordination compounds?

• Geometric isomerism

• Ionization isomerism

• Optical isomerism

• Structural isomerism, stereo isomerism, and coordination isomerism.
