WebApr 14, 2015 · We know empirically that isobutane (2-methylpropane) is more stable than n -butane. For example, their heats of formation (taken from the NIST WebBook) are − 134.2 k J / m o l and − 125.6 k J / m o l respectively, putting isobutane at ca. 10 k J / m o l lower in energy. But why is this so? Is there a physical or chemical explanation for this?
