Chapter 7.6, Problem 2Q

Interpretation Introduction

Interpretation:

The irons present in hemoglobin is either $\left({\text{Fe}}^{\text{2+}}\right)\text{ or }\left({\text{Fe}}^{\text{3+}}\right)$ state, so predict the paramagnetic property.

Concept Introduction:

Electronic configuration: The electronic configuration is the distribution of electrons of an given molecule or respective atoms in atomic or molecular orbitals.

Paramagnetic: The Paramagnetic properties are due to the presence of unpaired electrons, and from the realignment of the electron paths caused by the external magnetic field.

Diamagnetic properties: In diamagnetic materials all the electron are paired so there is no permanent net magnetic moment per atom.

General electronic configuration of d-block: These elements having common formula $\left(\text{n-1}\right){\text{d}}^{\text{1–10}}{\text{ ns}}^{\text{1–2}}$. The (n–1) stands for the inner d orbitals which may have one to ten electrons and the outermost ns orbital may have one or two electrons.
