Popis:	The methyl ketal formation is strongly exothermic (-14,6 Kcal/mole) with cyclohexanone and moderately so with cyclopentanone (-3,5 Kcal/mole) and with cyclobutanone (-2,5 Kcal/mole). An exceptional low reaction entropy is noted for cyclohexanone (-59 E.U.) and this is partly ascribed to the occurence of a high proportion of the twist conformation in cyclohexanone.
