# What is the disproportionation reaction of MgCl?

Jun 20, 2016

There is no disproportionation reaction.

#### Explanation:

Magnesium has only two oxidation numbers: 0 and +2.

Hence, there is no such compound as $\text{MgCl}$, in which $\text{Mg}$ would have an oxidation number of +1.

Even if you meant ${\text{MgCl}}_{2}$, it still wouldn’t disproportionate.

In a disproportionation reaction, $\text{Mg(+2)}$ could be reduced to $\text{Mg(0)}$, but it would also have to be oxidized to some higher oxidation number, and such a number does not exist.

Therefore, there is no disproportionation reaction.
