Calculate the electronegativity of fluor...

Calculate the electronegativity of fluorine from the following data:
`E_(H-H) = 104.4 kcal mol^(-1), E_(F-F) = 36.6 kcal mol^(-1)`
`E_(H-F) = 134.3 kcal mol^(-1), chi_(H) = 2.1`

Text Solution

Verified by Experts

Let the electroegativity of fluorine be `X_(F).` Applying Pauling's question.
`X_(F) - X_(H) =0.208[E_(H-F) -(E_(F-F) xx E_(H-H))^(1//2) ] ^(1//2)`
In this equation, dissociation energies are taken in kcal `mol ^(-1).`
`X_(F) =2.1 =0.208[134.6-(104.2xx36.6)^(1//2) ]^(1//2)`
`X _(f)=3.87`
