Question
Select the correct code about complex [Cr(NO2)(NH3)5][ZnCl4] :<br>(I) IUPAC name of compound is pentaamminenitrito-N-chromium (III) tetrachlorozincate(II)<br>(II) It shows geometrical isomerism<br>(III) It shows linkage isomerism<br>(IV) It shows coordination isomerism
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).
