Each of the following complex ions is either tetrahedral or square planar. On the basis of the number of unpaired electrons (given in parentheses) decide which is the correct geometry. Explain your answers, using valence bond theory telling what types of hybrid orbitals are being used by the metal ion in the complex.
a. Pt(NH3)2(NO2)2^2+ (2)
b. MnCl4^-2 (5)
c. NiCl4^-2 (2)
d. AuF4^- (0)
Enzyme labeling can be used to map the structure of the active site of an enzyme using an affinity label, a molecule that is structurally similar to the substrate
Why does OF2 have a single bond. Why not double bond? Wouldn't it be better to use a double bond and then O wouldn't have a lone pair and F would have one lone pair less? How can I know if to use single, double or triple bond
Name the kinds of attractive forces that must be overcome in order to do the following. (Select all that apply.) Boil liquid ammonia dipole-dipole forces dispersion forces hydrogen bonds ion-dipole forces ion-ion interparticle forces metallic bond..
