Dihydrogen reacts with dioxygen to form water. Write the name and formula of the product when the isotope of hydrogen which has one proton and one neutron in its nucleus is treated with oxygen. Will the reactivity of both the isotopes be the same towards oxygen? Justify your answer.

Answer:

Protium, Deuterium, and Tritium, despite sharing the same atomic number, these isotopes differ in their neutron count.

Heavy water (D2O) is formed when deuterium combines with oxygen.

Because the D–D link is stronger than the H–H bond, H2 is more reactive than D2 with oxygen. They wouldn’t be as reactive.
