Calculate the electronegativity of carbon from the following data: `E_(H-H)= 104.2 kcal mol^(-1), E_(C-C)= 83.1kcalmol^(-1), E_(C-H)= 98.8 kcal mol^(-1)``X_H=2.1`

Text Solution

Verified by Experts

`Delta = E_(C -H) - (E_(H-H) xx E_(C - C))^(1//2) = 98.8 - (104.2 xx 83)^(1//2) = 5.75 kcal`
Electronegativity = `chi_C - chi_H = 0.182 (5.75)^(1//2) =0.44`
Therefore , `chi_C = 0.44 + chi_H = 0.44 + 2.1 = 2.54`
`(chi_H = 2.1)`
