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

Text Solution

Verified by Experts

`chi_(C)-chi_(H)=0.208[E_(H-C)-(E_(H-H) xx E_(C-C)^(1//2)]^(1//2)`
`chi_(C)-2.1 =0.208[98.8-(104.2 83.1)^(1//2)]^(1//2)`
`chi_(C)=2/59`
