The experimental bond energy of HY differs from its calculated valueby 1.96 k.cals//"mole" . The electronegativity of 'y' is equal to

The difference in bond energy between the experimental and the calculated values of HY is 1.96 k cal mol^(-1) . The electronegativity of Y is (electronegativity of H is 2.1)

The bond energies of H - H, X - X and H - X are 104 K.Cal, 38K.Cal and 138 K.Cal respectively the electronegativity of 'X' is [sqrt(67) = 8.18]

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

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

Bond energies of H_2, F_2 and HF are respec tively 104.2, 36.6 and 134.6 k cal "mol"^(-1) . If the electronegativity value of hydrogen is 2.1, calculate the electro-negativity value of fluorine.

The concept of electronegativity (EN) is mainly to discuss the nature of chemical bonding, EN of an atom is the measure of its capacity to attract the shared electron pair towards itself. Linus Pauling compiled the values of EN that are most widely used, and that are displayed for a few elements in Table - 1. These values are based on bond energy differences between atoms bonded to themselves (e.g. A-A) and to other atoms (e.g. A-B), and an arbitary value of 4 to fluorine (most electronegative element) Mulliken regarded electronegativity as the average value of ionization energy and electron affinity of an atom EN= 1/2 (IE+EA). Both IE and EA are expressed in electron volts. In the Table-2, values of IE and EA for several elements are listed Table-3 shows the values of dipole moments and bond energies for simple molecules. Based upon the electronegativity difference of bonded atoms, which of the following about the chemical bond?
