The platinum complex of $\mathrm{NH}_{3}$ and $\mathrm{Cl}^{-}$ ligands is an anti-tumour agent. The correct isomeric formula of the complex and its precursor are:
(a)cis-$\mathrm{Pt}\left(\mathrm{NH}_{3}\right)_{2}\mathrm{Cl}_{2}$ and $\mathrm{PtCl}_{4}^{2-}$
(b)trans-$\mathrm{Pt}\left(\mathrm{NH}_{3}\right)_{2}\mathrm{Cl}_{2}$ and $\mathrm{PtCl}_{4}^{2-}$
(c)cis-$\mathrm{Pt}\left(\mathrm{NH}_{3}\right)_{2}\mathrm{Cl}_{2}$ and $\mathrm{Pt}\left(\mathrm{NH}_{3}\right)_{4}^{2-}$
(d)trans-$\mathrm{Pt}\left(\mathrm{NH}_{3}\right)_{2}\mathrm{Cl}_{2}$ and $\mathrm{Pt}\left(\mathrm{NH}_{3}\right)_{4}^{2-}$
Answer
Answer: A ✓ checked by 4AB · confidence high
Explanation
Cisplatin, cis-[Pt(NH₃)₂Cl₂], is made from [PtCl₄]²⁻ using the trans effect of chloride.
