This is a question that appeared on my last test. There is a small problem with it. But the teacher says it is still valid because there is a small chance of one of them being ampotheric. I'm just wondering, which one do you think it is?

Which of the following is amphoteric?
a H₂Mo²⁺
b CH₄
c Mo^-
d H⁺

How could Mo be minus?

It's one of the choices on the test.

It is easier to reject such a stupid examples.

To kkrizka - amphoteric, means - it can react with acid and bases to form reasonable compounds.
