Step-by-step solution
(a) [ Co ( NH ₃ )₅ NO ₂ ] Cl ₂ and [ Co ( NH ₃ )₅ ONO ] Cl ₂ - linkage Isomerism due to difference in binding site. (b) [ Cr ( NH ₃ )₆ ] [ Co ( CN )₆ ] and [ Cr ( CN )₆ ] [ Co ( NH ₃ )₆ ] - It is an example of coordination Isomerism due to exchange of ligands between the two coordination spheres. (c) [ Co ( NH ₃ )₅ ( SO ₄ ) ] Br and [ Co ( NH ₃ )₅ Br SO ₄ . - It is an example of Ionisation Iosmerism arising due to formation of different ions due to ionisation. The case arises due to exchange of ions between the coo
