Linus Pauling defined electronegativity as the power of an atom in a molecule to attract electrons. Given the bond disassociation enthalpies, $\varepsilon_{C-C} = 348\; \text{ kJ/mol}, \varepsilon_{C-H} = 412 \; \text{ kJ/mol}, \varepsilon_{H-H} = 436 \; \text{ kJ/mol}$, what is the Pauling elctronegativity of $C$?
