As shown in Fig. , alcohols have a large average A, generally >7. Near their M.P., A=8.1776, 9.0645, 8.7631, and 8.8537 correspond to methanol, ethanol, n-propanol, and isopropanol. For those molecules, symmetry is out of the question. It is too complicated. The diversity of conformations or the number of freedoms should concern the molecules' packing and entropy.
