Which of the following will give maximum number of isomer ?

Options

A. `[Ni(C_2 O_4) ("en")_2]^(2-)`
B. `[Ni("en")(NH_3)_4]^(2+)`
C. `[Cr(SCN)_2(NH_3)_4]^(+)`
D. `[Co(NH_3)_4 Cl_2]`

Answer

C

Explanation

`[Cr(SCN)_2 (NH_3)_4]^(+)` shows linkage, geometrical and optical isomersm. Hence produces maximum no. of isomers.
