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

A)  linkage, geometrical and ionization isomerism

B)  linkage, ionization and optical isomerism

C)  linkage, geometrical and optical isomerism

D)  ionization, geometrical and optical isomerism

Correct Answer: A

Solution :

 Idea This problem is based on isomerism in coordination compound, students are advised to keep in mind the concept of various types of isomerisms in coordination compounds. (i) \[N{{O}_{2}}\] is an ambidentate group. It can show linkage isomerism. (ii) The complex can show ionization isomerism with the complex \[[Co{{(N{{H}_{3}})}_{4}}N{{O}_{2}}Cl]N{{O}_{2}}\] (iii) The complex show geometrical isomerism. TEST Edge This concept is a good choice for JEE Main from where questions are asked in general so students are advised to study this concept very clearly and carefully, question involving reaction of various isomers may also be asked.
