Which of the following bonds has the highest bond energy?

Question

Which of the following bonds has the highest bond energy? (A) S-S (B) O-O (C) Se-Se (D) Te-Te

Tardigrade Admin · Accepted Answer

Expected high bond energy is in O-O due to high electron-negativity but due to smaller size ∴ will be repulsion and bond energy will be low ∴ [( S - S ) have more bond energy than O-O bond].

Q. Which of the following bonds has the highest bond energy?

$S - S$

$O - O$

$S e - S e$

$T e - T e$

Expected high bond energy is in $O - O$ due to high electron-negativity but due to smaller size
$∴$ will be repulsion and bond energy will be low
$∴ [(S - S)$ have more bond energy than $O - O$ bond].
