1.	Werner postulated that octahedral, tetrahedral and square planar geometrical shapes are more common in coordination compounds of ________(a) alkali metals(b) lanthanides(c) actinides(d) transition metalsI had been asked this question in an online quiz.My enquiry is from Werner’s Theory of Coordination Compounds in chapter Coordination Compounds of Chemistry – Class 12
Answer» Right option is (d) transition METALS The explanation: Transition metals BOND a bit differently from main group elements. They form coordinate covalent bonds and are often the central metal ion/atom of coordination complexes. Thus, OCTAHEDRAL, tetrahedral and SQUARE planar shapes are more common in transition metal central atoms.
