A) \[SeSe\]
B) \[TeTe\]
C) \[SS\]
D) \[OO\]
Correct Answer: C
Solution :
On moving downwards in a group as the size increases, element-element bond length increases and thus, the strength of element-element bond decreases. Since, the size of O atom is very small and its electronegativity is high, the combining O atom experience some repulsion. Due to which\[OO\]bond energy is lesser than the\[SS\] bond energy.
