Write the name of the platinum complex used in the treatment of cancer.
Answer:
Cisplatin — [PtCl2(NH3)2]
Explanation:
The platinum complex cisplatin (cis-diamminedichloroplatinum(II)) is an anticancer drug used in chemotherapy.
Its structure contains two ammonia and two chloride ligands in a cis configuration around the platinum(II) center: \[ [\text{PtCl}_2(\text{NH}_3)_2] \]
It works by binding to DNA and preventing cell division in cancer cells.

(ii) Write any one limitation of valence bond theory.
(i)[Ni(CN)₄]²⁻ and [Ni(CO)(_4)] have different structures, but do not differ in their magnetic behaviour. Explain.
(ii) Write the formula of Tetraamineaquachloridocobalt(III)chloride.
(i) Write two postulates of Werner's coordination theory.
(ii) Draw the geometrical isomers of [(NH_3)_3(NO_2)_3] and give their structures.
