- At what pH will Cl3CCO2H dissociate 50% in water? At what pH will it dissociate 90%? At what pH will it dissociate 10%?Which among the compounds is the most basic?(a) Tsomane and Nyiko were given a task of synthesising methylenecyclohexane 2. After a brief discussion with each other, Tsomane proposed Method A to synthesise 2 from cyclohexanone 1 while Nyiko proposed Method B that started from hydroxymethylcyclohexane 3. Each student believed that their proposed method is better than the other. (Scheme below) Ph THF A Ph Ph B H₂SO4 100 °C 3 OH (iii) In analysing both these methods, are there other possible alkene products other than methylenecyclohexane 2?
