H-H, X-X and H-X bond energies are 104 Kcal//"mole" 60 Kcal//"mole" and 101kcal//"mole" . Assuming the electronegativity of hydrogen to be 2.1 the electronegativity of unknown element X is (sqrt(19) = 4.36)

The bond energy of an O -H bond is 109 K. cal "mole"^(-1) . When a mole of water is formed

The bond energy of H_(2) is 104.3 k.cal mol^(-1) . It means that

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. The heat of formation of NO from its elements is +90 kJ mol^(-1) , What is the approximate bond dissociation enegry of the bond in NO ? BE_(N=N) = 941 kJ mol^(-1) BE_(O=O) = 499 kJ mol^(-1)
