Abstract: A critical re-examination confirms that the atom-bond connectivity index (ABC) is well reproducing the heats of formation of alkanes (H°f). Moreover, the simple empirical formula H°f  = – (a+b·ABC), with a = 65.98, b = 20.37, reproduces the heats of formation with an accuracy comparable to that of high-level ab initio and DFT (MP2, B3LYP) quantum chemical calculations.
