Discuss the consequences of high enthalpy of `H-H` bond in terms of chemical reactivity of dihydrogen.

Text Solution

Verified by Experts

Due to high enthalpy of H-H bond, hydrogen is quite unreactive at room temperature. However, at high temperatures or in presence of catalyst , it combines with many metals and non-metals to form hydrides.
