Question

Do all bonds have the same energy?

Answer 1

Bond energy:

1. Bond energy is the amount of energy released when $1mole$ of bonds are formed from the isolated gaseous atom.
2. The bond energy of a molecule is the average bond dissociation energy of all the chemical bonds present in that compound.
3. Hence, the bond strength between all the atoms in a molecule is not the same so the higher the bond strength of a bond between two atoms, the higher will be the bond energy.
4. For example: in $\mathrm{NaOH}$ the bond energy of $\mathrm{Na}$ with $\mathrm{O}$ is different than the bond energy of $\mathrm{O}$ with $\mathrm{H}$ .
5. Therefore, all bonds do not have the same energy.
