Show all work and use with full sentences Having calculated the electronegativity of H to be 2.33, Pauling set out to calculate the electronegativity of oxygen. He used the bond dissociation enthalpy of 180 kJ mol¹ for the O-O bond in H2O2, hydrogen peroxide. He used the O-H bond dissociation enthalpy of 472 kJ mol¹ for the polar (6+H-O-) water molecule and the bond dissociation enthalpy of 436 kJ mol¹ for the H-H bond of H2. What is the Pauling electronegativity of oxygen?
