Question

Red colour of oxyhemoglobin is due to which transition

Answer 1

It must be absorbing at blue green light and is therefore less stable

Answer 2

The red color of oxyhemoglobin is due to interligand π – π* transition.

Explanation:

Hemoglobin is responsible for the red color of blood. Hemes are the basic unit for building hemoglobin. Hemes have the capability of binding oxygen and iron molecules.

The blood cells are red because of the binding of oxygen and iron molecules. When oxygen and Fe bind together they exchange their orbitals bond and energy. During binding, the Fe molecule changes its oxygen state from +2 to +3.
