Acetic acid is among the top 10 chemicals manufactured in the U.S. each year. Most of the acetic acid is used to make vinyl acetate, which is turn is used to make polyvinyl acetate, which has a myriad of industrial uses, glue being one of them. The boiling point of acetic acid is 118°C. The thermal energy at this temperature is around 3.3 kJ./mol.Acetic acid tends to exist as two molecules that are held together by hydrogen bonds, as shown in the image.When acetic acid boils, which of the bonds indicated in the image as A and B is the thermal energy primarily used to break?
