\[\left[ Co{{\left( N{{H}_{3}} \right)}_{5}}N{{O}_{2}} \right]C{{l}_{2}}\] and \[\left[ Co{{\left( N{{H}_{3}} \right)}_{5}}\left( ONO \right) \right]C{{l}_{2}}\] are related to each other as

A) Geometrical isomers

B) Optical isomers

C) Linkage isomers

D) Coordination isomers

Correct Answer: C

Solution :

  Here more than one atom function as donor, as oxygen in first one and nitrogen in second, so they show linkage isomerism
