Question

For how many of the ligands below does M(X)₃ show both geometrical and optical isomerism? Let that number be X, and give the total number of stereoisomers of all those M(X)₃ complexes together. Ligands: en, ox²⁻, bipy, picolinate, 8-hydroxyquinolinate, trifluoroacetylacetonate, hexafluoroacetylacetonate, acac⁻, 2-aminophenolate

TestHub · Accepted Answer

Unsymmetrical chelates give M(AB)₃ with fac and mer forms, both chiral: picolinate, 8-hydroxyquinolinate, trifluoroacetylacetonate and 2-aminophenolate. So X = 4. Each such complex has 4 stereoisomers, so the total is 4 × 4 = 16.
