Hydrogen generally form covalent compounds. Give reason

Explanation

Hydrogen has one electron which it can either lose or , gain or share to acquire noble gas, i.e., helium gas configuration. Therefore, in principle, it can form either ionic or covalent bonds. But the ionization enthalpy of H is very high (`1312 KJ "mol"^(-1)`) and its electron gain enthalpy is only slightly (-73 KJ `"mol"^(-1)`). As a result, it does not have a high tendency to form bonds but rather prefers to form only covalent bonds.
