Formaldehyde, H2C=O, is known to all biologists because of its usefulness as a tissue preservative. When pure, formaldehyde trimerizes to give trioxane, C3H6O3, which, surprisingly enough, has no carbonyl groups. Only one monobromo derivative (C3H5BrO3) of trioxane is possible. Propose a structure for trioxane.

The disinfection of drinking water to control microbial contaminants can form chemical disinfection byproducts. These compounds result from the reaction of chlorine with naturally occurring organic matter (the dissolved molecules that give natural water the yellow-greenish color). One class of disinfection byproducts is the malodorous and unpalatable chlorophenols. 2,4-dichlorophenol is one compound of this class. a) Calculate the vapor pressure p*L of 2,4-dichlorophenol at 60 °C using Tb and structural information only OH .CI M, = 163.0 g/mol Tm = 43.7 °C Tp = 213.0°C %3D %3D %3D
