Chapter 23: Problem 10

Describe the interaction between a donor atom and a metal atom in terms of a Lewis acid-base reaction.

Short Answer

Expert verified
In a Lewis acid-base reaction, the donor atom (Lewis base) donates an electron pair to the metal atom (Lewis acid) forming a coordinate covalent bond between them.

Step by step solution

01

Understand Lewis Acid-Base Reaction

According to Lewis theory, a Lewis acid is a compound that can accept a pair of electrons from another species to form a coordinate covalent bond with it, while a Lewis base is a compound that donates a pair of electrons. Thus, in terms of Lewis acid-base reaction, donor atom refers to Lewis base, while metal atom refers to Lewis acid.
02

Interaction between Donor Atom and Metal Atom

The interaction between the donor atom (Lewis base) and a metal atom (Lewis acid) can be understood as a Lewis acid-base reaction. In this reaction, the donor atom donates an electron pair to the metal atom. This phenomenon is called a coordinate covalent bond.
03

Final Reaction

So, to summarise, a Lewis acid-base reaction involves the transfer of an electron pair from a Lewis base (the electron pair donor) to a Lewis acid (the electron pair acceptor). The interactions between these atoms where one is able to give electrons (donor atom) and the other wants to accept electrons (metal atom) leads to the formation of a stable bond between them.

What is the origin of color in a coordination compound?

Compounds containing the \(\mathrm{Sc}^{3+}\) ion are colorless, whereas those containing the \(\mathrm{Ti}^{3+}\) ion are colored. Explain.

The \(\mathrm{Co}^{2+}\) -porphyrin complex is more stable than the \(\mathrm{Fe}^{2+}\) -porphyrin complex. Why, then, is iron the metal ion in hemoglobin (and other heme-containing proteins)?

When aqueous potassium cyanide is added to a solution of copper(II) sulfate, a white precipitate, soluble in an excess of potassium cyanide, is formed. No precipitate is formed when hydrogen sulfide is bubbled through the solution at this point. Explain.
