1.	Dihydrogen reacts with dioxygen (O2) 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 isotope be the same towards oxygen? Justify your answer.
Answer» The isotope of hydrogen containing one proton and one neutron is deuterium (D). 2D₂(g) + O₂(g) → 2D₂O Deuterium oxide Since D-D bond is stronger than H – H bond, therefore, D₂ is less reactive towards oxygen than H₂.

Answer»

The isotope of hydrogen containing one proton and one neutron is deuterium (D).

2D₂(g) + O₂(g) → 2D₂O Deuterium oxide

Since D-D bond is stronger than H – H bond, therefore, D₂ is less reactive towards oxygen than H₂.
