What is he change in oxidation state of the metal when magnesium reacts with an alkyl bromide to give an alkylmagnesium bromide (Grignard reagent)?

Question

Quizplus · Accepted Answer

In the reaction, magnesium goes from an oxidation state of 0 to +2, since it loses two electrons to form Mg2+. The alkyl bromide, which typically has a halogen (-1) and a carbon (-4) oxidation state, now has a carbon that is less negative (since it has formed a bond with Mg, a less electronegative element) and a halogen that is less negative (since it has lost an electron). Therefore, the oxidation state of the metal (magnesium) has increased from 0 to +2.
