Question

which one has the highest bond energy?
a. o-o
b. s-s
c.Se-Se
d. Te-Te

Answer 1

b) s-s has the highest bond energy.

Answer 2

Explanation:

s-s is correct answer

S-S bond is stabilized and less effective in Se and Te due to full filled d-orbitals. -Also, the non bonding electron pair of O-O bonds have strong repulsion which makes it weak in comparison with S-S bond. -So, the S-S bond has highest bond energy.
