Which one has the highest magnetic moment value: The bond are formed by overlap of atomic orbital of metal with that of C-atom of carbon monoxide in following sequence: Quite obviously, they absorb radiations corresponding to different wavelengths and frequencies from the -visible region of light, VIBGYOR and the transmitted colours are also different. Specify the oxidation numbers of the metals in the following coordination entities: Share this:
Indicate the types of isomerism exhibited by the.
When dissolved in water, they give different ions in solution which can be tested by adding AgN0 3 solution and BaCl 2 solution, i. Predict the number of unpaired electrons in the square planar [Pt CN 4 ] 2- ion.
The hexaquomanganese II ion contains five unpaired electrons, while the hexacyano ion contains only one unpaired electron.
Explain using Crystal Field Theory. Thus, the overall dissociation constant is. Every cation has a fixed number of secondary valencies which are directed in space about central metal ion in certain fixed directions, e.
In modern theory, it is now referred as coordination number of central metal atom or ion. Explain why.
CuSO 4 solution mixed with aqueous ammonia in 1: Coordination entity: Coordination polyhedron: Spatial arrangement of ligands defining the shape of complex. Give two examples for each.
A molecule or an ion which has only one donor atom to form one coordinate bond with the central metal atom is called unidentate ligand, e. A molecule or ion which contains two donor atoms and hence forms two coordinate bonds with the central metal atom is called adidentate A molecule or an ion which contains two donor atoms but only one of them forms a coordinate bond at a time with the central metal atom is called.
Coordination compounds exhibit stereo isomerism and structural isomerism. Two types of stereoisomerism and their examples are as follows. These are obtained by keeping the position of one of the ligand, say NH3 fixed and rotating the positions of others. This type of isomers do not show any optical isomerism. Optical isomerism only rarely occurs in square planar or tetrahedral complexes and that too when they contain unsymmetrical chelating ligand.
Aqueous copper sulphate solution blue in colour gives: Explain these experimental results. Why is it that no precipitate of copper sulphide is obtained when H 2 S g is passed through this solution? First cupric cyanide is formed which decomposes to give cuprous cyanide and cyanogen gas.
Cuprous cyanide dissolves in excess of potassium cyanide to form the complex, K 3 [Cu CN 4 ], Thus, coordination entity formed in the above reaction is [Cu CN 4 ] Hence, no precipitate,with H 2 S is formed. Discuss the nature of bonding in the following coordination entities on the basis of valence bond theory: Explain the difference between a weak field ligand and a strong field ligand.
The arrangement of ligands in order of their increasing field strengths, i. When the ligands approach a transition metal ion, the d-orbitals split into two sets, one with lower energy and the other with higher energy. Explain why? Hence, it is coloured. The d-d transition absorbs red light and the complementary light emitted is green. Give two examples for each.
Specify the oxidation numbers of the metals in the following coordination entities:. List various types of isomerism possible for coordination compounds, giving an example of each. How many geometrical isomers are possible in the following coordination entities? Write all the geometrical isomers of and how many of these will exhibit optical isomers?
What is the coordination entity formed when excess of aqueous KCN is added to an aqueous solution of copper sulphate? Why is it that no precipitate of copper sulphide is obtained when is passed through this solution?
Discuss the nature of bonding in the following coordination entities on the basis of valence bond theory:. Draw figure to show the splitting of d orbitals in an octahedral crystal field. Ncert solution class 12 Chemistry includes text book solutions from both part 1 and part 2.
