Pauling 's electronegativity scale is based upon experimental values of

Options

A. Atomic radii
B. Bond energies
C. Electronegativities
D. Electron affinity

Answer

B

Explanation

`X_(A)-X_(B)=0.208[E_(A-B)-(E_(A-A)xxE_(B-B))^(1//2)]^(1//2)`
Where `X_(A)` and `X_(B)` are `EN` of atom `A` and `B` , `E_(A-A),E_(B-B)` and `E_(A-B)` are bond eneriges of molecules of `A_(2),B_(2) and AB`.
