Dihydrogen appears the homonuclear diatomic molecule H2, connected by a strong covalent bond. It is the lightest known molecule with a molecular weight of about 2.016 u. At room temperature it is a colorless, odorless, highly flammable gas. Nonpolarity limits its solubility in water. A strong H–H bond gives a dissociation enthalpy near 435 kJ/mol, which governs its chemical reactivity and inertness under ambient conditions.

edurev.inDihydrogen - Introduction A hydrogen atom weighs the least. Hydrogen is a gas with the formula 𝐻2 that exists normally. It is made up of diatomic molecules. In addition to being very combustible, it has no colour or smell. With approximately 75% of all normal matter made up of hydrogen, it is the most prevale
www.tutorialspoint.comDihydrogen 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.
