Question

increasing order of bond dissociation of halogen

Answer 1

Trend in Bond Dissociation Energy (Bond DissociationEnthalpy) in Halogens: ... Since atomic size increases from chlorine to Iodine, bond length increases from chlorine to iodine. As bond length increases from Cl to I. Bond dissociation energydecreases from chlorine to Iodine molecule..
hope is helps!!
