Abstract: In this paper, the principle of corresponding states was used when conducting a comparative analysis of the temperature dependences of the isobaric heat capacity of aliphatic alcohols and their fluorosubstituted analogues. For the heat capacity, both literature experimental data and simulated data, obtained using artificial neural networks, were applied. The isobaric heat capacity for the aliphatic alcohols in the absolute values in a wide temperature range at constant pressure is smaller than that for the corresponding fluorosubstituted analogues. The comparison of the heat capacity data on the aliphatic alcohols and their fluorosubstituted analogues with the heat capacity of water, for which there is a hydrogen bond network, and comparison of the corresponding data with the heat capacity of hydrogen peroxide, where there are hydrogen bonds, but the network is absent, indicates that the change in the physical properties of alcohols upon fluorosubstitution is associated with the hydrogen bond density.
