Question

Which one of the following has largest number of isomers?

A. $${\left[ {Ir{{\left( {P{R_3}} \right)}_2}H\left( {CO} \right)} \right]^{2 + }}$$
B. $${\left[ {Co{{\left( {N{H_3}} \right)}_5}Cl} \right]^{2 + }}$$
C. $${\left[ {Ru{{\left( {N{H_3}} \right)}_4}C{l_2}} \right]^ + }$$
D. $${\left[ {Co{{\left( {en} \right)}_2}C{l_2}} \right]^ + }\,\left( {{\text{R = alkyl}}\,{\text{group,}}\,{\text{en = ethylenediamine}}} \right)$$  
Answer :   $${\left[ {Co{{\left( {en} \right)}_2}C{l_2}} \right]^ + }\,\left( {{\text{R = alkyl}}\,{\text{group,}}\,{\text{en = ethylenediamine}}} \right)$$
Solution :
Isomers
$$\mathop {{{\left[ {Ru{{\left( {N{H_3}} \right)}_4}C{l_2}} \right]}^ + }}\limits_{{\text{cis}}\,\,{\text{and}}\,{\text{trans}}} ,\mathop {{{\left[ {Co{{\left( {N{H_3}} \right)}_5}Cl} \right]}^{2 + }}}\limits_{{\text{none}}} ,$$
$$\mathop {{{\left[ {Ir{{\left( {P{R_3}} \right)}_2}H\left( {CO} \right)} \right]}^{2 + }}}\limits_{{\text{cis}}\,\,{\text{and}}\,{\text{trans}}} ,$$  $$\mathop {{{\left[ {Co{{\left( {en} \right)}_2}C{l_2}} \right]}^ + }}\limits_{{\text{cis}}\,\,{\text{and}}\,{\text{trans and}}\,{\text{optical}}\,{\text{isomers}}} $$
