Hemoglobin exists in two predominant forms in our bodies.
One form, known as oxyhemoglobin, has $O_{2}$ bound to the metal ion (A) and the other, known as deoxyhaemoglobin, has a water molecule bound instead. Oxyhemoglobin is a low spin complex that gives arterial blood its red colour and deoxyhaemoglobin is a high spin complex that gives venous blood its darker colour.
If the electronic configurations of metal ion(A) in oxyhemoglobin and deoxyhaemoglobin are $t_{2 g}^{x} e_{g}^{y}$ and $t_{2 g}^{a} e_{g}^{b}$ Respectively, then the value of $\frac{x + y}{a + b}$ is

Question

Hemoglobin exists in two predominant forms in our bodies.
One form, known as oxyhemoglobin, has

O_{2}

bound to the metal ion (A) and the other, known as deoxyhaemoglobin, has a water molecule bound instead. Oxyhemoglobin is a low spin complex that gives arterial blood its red colour and deoxyhaemoglobin is a high spin complex that gives venous blood its darker colour.
If the electronic configurations of metal ion(A) in oxyhemoglobin and deoxyhaemoglobin are

t_{2 g}^{x} e_{g}^{y}

and

t_{2 g}^{a} e_{g}^{b}

Respectively, then the value of

\frac{x + y}{a + b}

is

Infinity Learn · Accepted Answer

Metal ion (A) is: Fe2+3d6In oxyhaemoglobin, O2 is categorized as strong field ligand and the electronic configuration of metal ion is t2g6eg0.In deoxyhaemoglobin, the electronic configuration of metal ion is t2g4eg2.
