Cyclohexanol dehydration equation
WebConclusions : The results support that the acid-catalyzed dehydration of 2-methycyclohexanol was successful. The GC percentages support Sayzteff’s rule; the … WebThe synthesis of cyclohexene from cyclohexanol is an example of elimination reaction. Cyclohexanol, 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 strong base making it a poor leaving group. The reaction will then be followed by the ...
