Dihydrogen forms the homonuclear diatomic molecule H2, made through a covalent H–H bond. It is the lightest known molecule with a molecular weight of about 2.016 u. In normal conditions it appears as a colorless, odorless, highly flammable gas. Its nonpolar nature makes it sparingly soluble in water. A strong H–H bond gives a dissociation enthalpy near 435 kJ/mol, influencing its reactivity and inertness at room temperature.

www.geeksforgeeks.orgDihydrogen is the homonuclear diatomic molecule formed from two hydrogen atoms. This molecule features a covalent bond between two hydrogen atoms, satisfying each of their required duet configurations. Since hydrogen is the lightest element on the modern periodic table, dihydrogen is the lightest known molecule. Since the standard atomic weight of the hydrogen atom is 1.008u, the molecular weight of the dihydrogen molecule is 2.016 atomic mass units.
