What is the disproportionation reaction of #MgCl#?

Answer 1

There is no disproportionation reaction.

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

Hence, there is no such compound as #"MgCl"#, in which #"Mg"# would have an oxidation number of +1.

Even if you meant #"MgCl"_2#, it still wouldn’t disproportionate.

In a disproportionation reaction, #"Mg(+2)"# could be reduced to #"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.

The disproportionation reaction of MgCl is the reaction in which a single substance undergoes both oxidation and reduction simultaneously, producing two different oxidation states of the same element. However, MgCl does not undergo a disproportionation reaction because it contains only one oxidation state of magnesium (+2) and one oxidation state of chlorine (-1). Disproportionation reactions typically occur with elements that have multiple oxidation states.

Answer from HIX Tutor

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
