WebThe molecule [ P d C l X 4] X 2 − is diamagnetic, which indicates a square planar geometry as all eight d electrons are paired in the lower-energy orbitals. However, [ N i C l X 4] X 2 − is also d 8 but has two unpaired electrons, indicating a tetrahedral geometry. Why is [ P d C l X 4] X 2 − square planar if C l is not a strong-field ligand? WebSep 13, 2015 · The tetrahedral complex [ C o C l X 4] X − has everything that the octahedral [ C o ( H X 2 O) X 6] X 2 + has except the centre of symmetry. Because centrosymmetry is missing, the Laporte rule is no longer valid and every photon of the correct energy can excite electrons. More excitation equals a stronger extinction.
WebJan 20, 2015 · [Co(H 2O)6]2+ +4Cl− ⇌ CoCl2− 4 +6H 2O The [Co(H 2O)6]2+ ion is pink, while the CoCl2− 4 ion is blue. The forward reaction is endothermic, which means the equilibrium could be written as [Co(H 2O)6]2+ +4Cl− +heat ⇌ CoCl2− 4 +6H 2O We can say that heat is a reactant in this equilibrium.
