hich of the following bonds has the highest bondenergy?(2) O-o(3) Se-Se(4) Te-Te |
|
Answer» The answer is S-S bond, it is because sulphur forms stronger covalent bond than Se and Te and the S-S bond is stabilized bypπ-dπbonding which is absent in O-O (due to absence of d-orbtals) 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. |
