Step-by-step solution

Ziegler catalyst → Titanium Ziegler- Natta catalyst contains two parts – a transition metal compound and an organoaluminum compound. Organoaluminum compounds contain bonds between aluminum and carbon atoms. Examples of Ziegler-Natta catalysts include TiCl 4 + Et 3 Al and TiCl 3 + AlEt 2 Cl . So, if we want to write the chemical formula of one of the Ziegler-Natta catalysts then it can be represented as TiCl 4 Al ( CH 3 ) 2 ( CH 2 ) 2 Cl . Blood pigment → Iron Haemoglobin: RBCs/erythrocytes play an important role in
