Question

Which of the following bonds has the highest bond energy?

• A. $O-O$
• B. $S-S$
• C. $Se-Se$
• D. $Te-Te$

Answer 1

Answer: (B)

$\text{S-S}$ bonds has the highest bond energy as the size increases from $\text{S}$ to $\text{Te}$ , the bond dissociation energy decreases the non bonding electron pair of $\text{O-O}$ bonds have strong repulsion which makes it weak in comparison with $\text{S-S}$ bond so, the $\text{S-S}$ bond has highest bond energy.
