Question

How bond energies and bond lengths of molecule help us in predicting their chemical properties? Explain with example

Answer 1

Explanation:

Bond length: Bond length or bond distance is the equilibrium distance between the nuclei of two atoms which form a covalent bond.

Bond energy : Bond energy or bond dissociation energy is the energy needed to break a covalent bond between two atoms of a diatomic covalent compound in its gaseous state.

If the nature of the bond between the same two atoms changes, the bond length also changes.

For example,

the bond lengths between two carbon atoms are :

C-C > C = C > C = C

When bond length decreases, then bond dissociation energy increases.

When bond length increases, then bond dissociation energy decreases.
