Discuss the consequences of high enthalpy of H–H bond in terms of chemical reactivity of dihydrogen

Asked by Abhisek | 1 year ago |  116

##### Solution :-

The ionization enthalpy of H–H bond is higher ($$1312 kJ mol^{–1}$$) which shows  that hydrogen has a low tendency to form H+ ions. Its ionization enthalpy value is comparable to that of halogens. Hence, it forms

→ a large number of covalent bonds

→ diatomic molecules (H2)

→ hydrides with element

Hydrogen does not possess metallic characteristics (lustre, ductility, etc.) like metals because ionization enthalpy is very high.
