Provide an MO energy-level diagram for Ca metal and show two different scenarios, one in which the 4s and 3d bands are separated and another where these bands overlap. Explain which diagram demonstrates a substance with high electrical conductivity. Concept introduction: There are two theoretical models for bonding in metals which are the electron-sea model and the molecular orbital theory. Molecular orbital theory is the combination of atomic orbitals of individual atoms to form molecular orbitals. The number of molecular orbitals formed is the same as the number of atomic orbitals combined. A band is a set of MOs that are very closely spaced in energy and consequently MO theory for metals is often called band theory. To classify: The MO energy-level diagrams for Ca and which is more conductive.

A student proposes the transformation below in one step of an organic synthesis. There may be one or more reactants missing from the left-hand side, but there are no products missing from the right-hand side. There may also be catalysts, small inorganic reagents, and other important reaction conditions missing from the arrow. • Is the student's transformation possible? If not, check the box under the drawing area. . If the student's transformation is possible, then complete the reaction by adding any missing reactants to the left-hand side, and adding required catalysts, inorganic reagents, or other important reaction conditions above and below the arrow. • You do not need to balance the reaction, but be sure every important organic reactant or product is shown. + T X O O лет-ле HO OH HO OH This transformation can't be done in one step.
