Electron transitions of greater energy magnitude occur between:
A- two more interior electron shells or two electron shells with large differences in nB- two more exterior electron shells or two electron shells with large differences in nC- two more interior electron shells or two adjacent electron shells D- two more exterior electron shells or two adjacent electron shells
A Grignard reagent is an organomagnesium halide (or R-Mg-X). Explain the difference in the reactivity of the carbon bonded to the halide in an alkyl halide (R-X) versus the carbon bonded to the magnesium in a Grignard reagent.
