Webb) The rate of dehydration of cyclohexanol using 85% phosphoric acid is conveniently fast. c) The product is easily purified by distillation at a readily accessible temperature, (83 oC). d) When heated with strong acids catalysts (most commonly H2SO4, H3PO4), alcohols typically undergo a 1,2-elimination reactions to generate an alkene and water. WebCyclohexanol, a secondary unsaturated alcohol, undergoes dehydration reaction to form a good leaving group which is H 2 0 because the OH group of an alcohol is a very …
WebFor dehydration of cyclohexanol, phosphoric acid is used. The phosphoric acid protonates the most basic atom ... To transition from an alcohol to an alkene, the alcohol … WebFigure 1.
