question_answer

\[\left[ Co{{\left( N{{H}_{3}} \right)}_{4}}{{\left( N{{O}_{2}} \right)}_{2}} \right]\,Cl\] exhibits                                         

A)  ionisation isomerism, geometrical isomerism and optical isomerism

B)  linkage isomerism, geometrical isomerism and optical isomerism

C)  linkage isomerism. ionisation isomerism and optical isomerism

D)  linkage isomerism, ionisation isomerism and geometrical isomerism

Correct Answer: D

Solution :

\[-N{{O}_{2}}\] has two types of linkage   Hence, it will show linkage isomerism.   \[\left[ Co {{\left( N{{N}_{3}} \right)}_{4}} {{\left( N{{O}_{2}} \right)}_{2}} \right] Cl\] and \[\left[ CO {{\left( N{{N}_{3}} \right)}_{4}}\,NO{{ & }_{2}}Cl \right]N{{O}_{2}}\] are ionisation isomers.
