d. By using the combination of these species (Fe,NH3,Cl and CO), write an appropriate chemical equation for each of the preparative stated method. The final product should be in octahedral shaped structure ( ML5;M= metal centre and L= ligand). Dengan menggunakan kombinasi spesies (Fe,NH3,Cl dan CO), tuliskan persamaan kimia bagi setiap kaedah penyediaan yang dinyatakan. Hasil akhir hendaklah berbentuk oktahedral ( ML6;M= pusat logam and L= ligan. i. Addition reaction (3 marks) Tindak balas penambahan (3 markah) ii.
