Question

Which of the following molecule has highest bond energy?

F-F,N-N,C-C,O-O
​

Answer 1

Answer:

O2 will have highest bond energy... because in F2 the bond energy is less due to small size of fluorine atom so Interelectronic repusion takes place in between both the F atoms.

Answer 2

C-C molecule has highest bond energy.

Explanation:

• As all the given molecules are bonded together through single bond. And, more is the bond order of a molecule more closely its atoms will be bonded together. As a result, more strong will the bonding between its combining atoms.

• Moreover, there will be presence of lone pair of electrons on fluorine, nitrogen and oxygen atoms. Hence, there will occur lone pair-lone pair repulsion between F-F, N-N and O-O molecules. Due to which there will occur an increase in its bond length and decrease in bond energy.

• Therefore, only C-C molecule will have high bond energy as there are no lone pairs present on carbon atom.
