Question
Which of the following isomerism is not possible for complexes having molecular formulae :<br>(i) Pt(SCN)2 \cdot 3PEt3 (ii) CoBr \cdot SO4 \cdot 5NH3 (iii) FeCl2 \cdot 6H2O
π‘ Solution & Explanation
Step 1: Evaluate statement I: The IUPAC name is pentaamminenitrito-N-chromium(III) tetrachlorozincate(II) which is correct because the cation has charge +2 and anion has charge -2. Evaluate statement II: Geometrical isomerism is not shown by octahedral complexes with formula [MA5B], so this is incorrect. Step 2: Evaluate statement III: The compound contains the ambidentate nitro (NO2^-) ligand, which can coordinate through either N or O, so it shows linkage isomerism. Evaluate statement IV: The complex has both a complex cation and a complex anion, which can exchange ligands to form coordination isomers. Step 3: Since statements I, III, and IV are correct, the correct option is (b).
