How is a complex ion a Lewis adducts?

Short Answer

Expert verified

Complex ions are Lewis adducts because they are formed from Lewis acids (the central atoms or central ion) to which Lewis bases (ligands) attach to.

Step by step solution

01

Definition of Coordination Compound

A coordination complex consists of a central atom or ion, which is sometimes metallic and is termed the coordination centre, and a surrounding array of bound molecules or ions, that are successively called ligands or complexing agents.

02

Solve the given statements

When a Lewis base and a Lewis acid react and form a compound, this compound is termed Lewis adduct. Lewis adducts contain coordinate covalent bonds where the electrons within the bond come from the Lewis base. Complex ions are Lewis adducts because they're formed from Lewis acids (the central atoms or central ion) to which Lewis bases (ligands) attach to.

Which of these ligands can participate in linkage isomerism?

  1. NO2-
  2. SO2
  3. NO3-

Explain with Lewis structures.

The metal ion in platinum(IV) complexes, like that in cobalt(III) complexes, has a coordination number of 6 and often has Cl-ions and NH3molecules as ligands. For the traditional (before the work of Werner) formulasPtCl4·6NH3and localid="1663359663004" PtCl4·4NH3,(a) give the modern formula and charge of the complex ion, and(b) predict the moles of ions per mole of compound dissolved and moles of AgCl formed with excess AgNO3.

Give the electron configuration of (a) La; (b) Ce3+ (c) Es; (d) U4+.

Werner prepared two compounds by heating a solution ofPtCl2with triethyl phosphine, PC2H53which is an excellent ligand for Pt. The two compounds gave the same analysis: Pt, 38.8%, Cl,14.1%, C,28.7%, P,12.4%and H,6.02%. Write formulas, structures, and systematic names for the two isomers.

When MCl4(NH3)2is dissolved in water and treated with AgNO3, 2 mol of AgCl precipitates immediately for each mole of MCl4(NH3)2. Give the coordination number of M in the complex.
