Question

E.N is the tendency of an atom to attract the
shared electron pair towards it in a covalent
bond. Since it is a relative property it has no
units. Hence various scaled are proposed
such as Mullikan scale, Pauling scale, Allred-
Rochowe scale. The most accepted is of
pauling based on bond energy data and more
particularly on lonic-covalent bond resonance
energy. While Mulliken scale applicable to
mono valent elements says that E.N is the
average of 1.P and E.A. Electro negativity on
Mullikien scale is 2.8 times more than that of
calculated from Pauling scale.
Q. H - H, X - X, and H
X bond
energies are 104 kcal/mol, 38 kcal/mol and
135 kcal/mol respectively. Electro negativity
of 'X' is​
