Question
Hydrogen generally forms covalent compounds. Give reason.
Solution
Because of ionization enthalpy, hydrogen resembles more with halogens, is 520 kJ mol–1, F is 1680 kJ mol–1 and that of his 1312 kJ mol–1. Like halogens, it forms a diatomic molecule, combining with elements to form hydrides and a large number of covalent compounds.
