Which of the following statements is NOT true regarding dihydrogen?

Dihydrogen reduces oxides and ions of metals that are less reactive than iron, not more reactive. For example, it reduces copper(II) oxide to copper, but cannot reduce aluminium oxide or magnesium oxide.

Dihydrogen reacts violently with fluorine even in the dark at very low temperatures (-250\ ^{}^{\circ}\text{C}).

It is used in the industrial preparation of methanol from carbon monoxide: $CO + 2H_2 \xrightarrow{\text{catalyst}} CH_3OH$.

It reacts with highly electropositive alkali metals at high temperatures to form ionic metal hydrides.

Answer: It reduces oxides and ions of metal, having more reactivity than iron.
