There are 4 basic kinds of chemical reactions in organic chemistry: combination, elimination, substitution, and rearrangement. Learn about dehydration. The dehydration of 2, 3-dimethyl-2-pentanol gives four different alkene products including E and Z isomers. The product analysis.
In the E1 mechanism. B) The rate of dehydration of cyclohexanol using 85% phosphoric acid is conveniently fast. The protonated alcohol is the substrate that undergoes an E1 elimination which, remember, starts with the loss of the leaving group: The loss of the leaving group is a heterolytic cleavage of the C-O bond and as expected, it is the rate-determining step of the reaction. Draw the major product for the dehydration of 2-pentanol. one. Draw the major product(s) of the reaction of 2-methyl-I-propanol, primary alcohol with these reagents: KzCrzOz, HzSO4. Always draw alkenes with the correct 120° bond angles around the C=C bond as shown in the diagrams for the cis and trans isomers above.
