The scale which is based on an empirical relation between the energy of a bond and the electro negativities of bonded atoms is:
Correct Answer is Option : Pauling scale
Pauling Scale : An arbitary value of 4.0 has been assigned to Fluorine [the most electro negative element ] and the electronegatives of another elements have been calculated against this standard by the application of following formula .
XA- XB= 0.102[E A-B - 1/2[ E A-A + E B-B )¹/²
where X A and Xb are electro negativities of two atoms A and B.
EA-B, EA-A and EB-B are bond energies of molecules AB, A2 and B2 respectively in kJ per mole.
