The complex used as an anticancer agent is

Options

A. mer - `[Co(NH_3)_3Cl_3]`
B. cis - `[PtCl_2(NH_3)_2]`
C. cis - `K_2[PtCl_2Br_2]`
D. `Na_2[CoCl_4]`

Answer

B

Explanation

Cis-`[PtCl_2(NH_3)_2]` is used as an anti-cancer agent, called as cisplatin and is highly toxic. On injecting, the more reactive Cl group are lost so the Pt atom bonds to a N atom in guanosine ( part of the DNA molecule). Those cells which are undergoing cell division are attacked by cisplatin.
