WebJun 17, 2024 · N-butane has an enthalpy of formation of $\pu {-125.6 kJ/mol}$, whereas it is $\pu {-134.2kJ/mol}$ for 2-methylpropane. When comparing the heat set free at the combustion process, why is it higher for n-butane? Isn't the enthalpy of formation the negative of enthalpy of combustion and therefore 2-methylpropane should be higher? … WebThis slight difference is enough to give butane and 2-methylpropane different physical properties: for instance while butane boils at -0.5°C, 2-methylpropane boils at a lower temperature, -11.7°C. (The lower boiling point is a result of the more compact structure of the 2-methylpropane isomer, which has less surface area than the straight ...
