Similar complex dependences for HE are observed in aqueous mixtures of 1,4-dioxan, 1,3-dioxan, trimethylene oxide, ethylene glycol dimethyl ether (Morcom and Smith, 1970 Nakayama and Shinoda, 1971), or 1,3-dioxolan (Blandamer et al., 1969b). However, not all TA mixtures have this S-feature, e.g. alkyl substituted amides + water (Assarson and Eirich, 1968), and t-butylamine + water at 313 K (Duttachoudhury and Mathur, 1974). The HE dependences for TA systems are very complex. Even for ethanol-water mixtures at 298 K... 

There are three dioxane isomers 1,2-dioxane, 1,3-dioxane, and 1,4-dioxane. One of these acts like an ether and is an excellent solvent for Grignard reactions. Another one is potentially explosive when heated. The third one quickly hydrolyzes in dilute acid. Show which isomer acts like a simple ether, and explain why one of them is potentially explosive. Propose a mechanism for the acid hydrolysis of the third isomer.
