Question

why H-H bond enthalpy is the highest for a single bond of nay element​

Answer 1

Answer:

There is a general trend in that the shorter the bondlength, the higher the bond energy. Hydrogen has a relatively small atom and short bondlength hence very strong strong attractions between the atoms which will consenquently increase its bond dissociation ethalpy.

Answer 2

Answer:

Hi I hope This anwer helps u

Explanation:

Atomic hydrogen is very reactive whereas the molecular hydrogen are quite stable . The chemical behaviour of dihydrogen is determined , to a large extent by bond dissociation enthalpy . The H-H bond dissociation enthalpy is the highest for a single bond between two atoms of any element.
