Bond energies can be obtained by using the following relation: `DeltaH (reaction) = sum`Bond energy of bonds, broken in the reactants `-sum` Bond energy fo bonds, formed in the products  Bond enegry depends on three factors:  a. Greater is the bond length, lesser is the bond enegry.  b. Bond energy increases with the bond multiplicity.  c. Bond enegry increases with electronegativity difference between the bonding atoms.   Bond enegry of differene halogen molecules will lie in the sequences
