Odisha Board Solutions for Chapter: Co-ordination Compounds, Exercise 1: QUESTIONS

Which type of square planar complexes show cis-trans isomerism ?

Which type of octahedral complexes show geometrical isomerism ?

Discuss in brief the Crystal Field theory. How does it differ from Valence Bond theory? Explain the fact that ${\left[{\mathrm{CoF}}_6\right]}^{3-}$ is paramagnetic whereas ${\left[\mathrm{Co}{\left({\mathrm{NH}}_3\right)}_6\right]}^{3+}$ is diamagnetic although both are octahedral.

Describe the bonding in ${\left[\mathrm{Fe}{\left({\mathrm{H}}_2\mathrm{O}\right)}_6\right]}^{3+}$ and ${\left[\mathrm{Fe}{\left(\mathrm{CN}\right)}_6\right]}^{3-}$ in terms of Valence Bond theory and Crystal Field theory.

Tetrahedral complexes do not show low spin configuration - Explain.

Discuss briefly how Crystal Field theory explains the magnetic properties of complexes of transition metals.

 Discuss the structure of following complex on the basis of CFT.

${\left[\mathrm{Co}{\left({\mathrm{NH}}_3\right)}_6\right]}^{3+}$

 Discuss the structure of following complex on the basis of CFT.

${\left[\mathrm{Fe}{\left(\mathrm{CN}\right)}_6\right]}^{4-}$
