उत्तर
S-S
Explanation:
Sulphur has a stronger S-S single bond due to its ability to catenate and form stable S-S bonds in rings and chains. As we go down the group from sulphur to selenium and tellurium, bond energies decrease because of increasing atomic size and poorer orbital overlap. Hence, S-S bond energy is higher than O-O, Se-Se, and Te-Te bonds.
