Question

Which of the following will give maimum number of isomers ?

• A. $\left[Co\right(N{H}_3{)}_{4}C{l}_2]$
• B. $\left[Ni\right(en\left)\right(N{H}_3{)}_4{]}^{2+}$
• C. $\left[Ni\right(C_2{O}_4\left)\right(en{)}_2{]}^{2-}$
• D. $\left[Cr\right(SCN{)}_2(N{H}_3{)}_4{]}^{+}$

Answer 1

The correct option is D $\left[Cr\right(SCN{)}_2(N{H}_3{)}_4{]}^{+}$

This complex $\left[Cr\right(SCN{)}_2(N{H}_3{)}_4{]}^{+}$ shows cis, trans and linkage isomers.
