[2015] 1. [Cr(NH 3 ) 6 ][Cr(SCN) 6 ] and [Cr(NH 3 ) 2 (SCN) 4 ][Cr(NH 3 ) 4 (SCN) 2 ] are examples of what type of isomerism? (A) Ionisation isomerism (B) Linkage isomerism (C) Coordination isomerism (D) Solvate isomerism Correct Answer: (C) Coordination isomerism Solution: Coordination isomerism occurs when there is an interchange of ligands between the cationic and anionic coordination spheres of different metal ions. [2016] 2. Which of the following is a neutral complex? (A) [Pt(NH 3 ) 2 Cl 2 ] (B) [Co(NH 3 ) 6 ]Cl 3 (div) [Ni(NH 3 ) 6 ]Cl 2 (D) K 4 [Fe(CN) 6 ] Correct Answer: (A) [Pt(NH 3 ) 2 Cl 2 ] Solution: A neutral complex has no net charge. In [Pt(NH 3 ) 2 Cl 2 ], the +2 charge of Pt is balanced by two -1 charges of C...
