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)^(1//2)= 5.75 kcal`
Electronegativity= `chi_(C)-chi_(H)= 0.182(5.75)^(1//2)= .44`
therefore, `chi_(C)= 0.44+chi_(H)= 0.44+2.1= 2.54`
`(chi_(H)= 2.1)`
