Witrynaform, dichloromethane and acetone were measured from (298 to 323) K and are summarized in Table 1. As shown in Fig. 1 the mole fraction solubility x of caffeine was correlated as a function of temperature as follows Ln x=A+B ( T/K) (1) The parameters A and B for the solvents and root mean square deviations are listed in Table 2. http://bibliotecadigital.uns.edu.ar/pdf/laar/v40n3/v40n3a12.pdf Witrynaand a boiling point of 40°C. Why is the boiling point of dichloromethane 92º higher than that of difluoromethane? Which of the following explains why dichloromethane has the higher boiling point? a. CH 2F 2 is more polar and thus must have stronger binding forces. With stronger intermolecular attraction, of course CH 2F 2 will have a lower ... chloe harvey
