Is it possible 3-methyl-butanol --> 2-methyl-2-butene under acid catalized condition? If possible write out rxn.
图二 : when trans-2-methyl cyclohexanol is subjected to acid catalyzed dehydration, the major product is 1-methylcyclohexene. E1 elemination mechanism. R-OH is protonated to give R-OH2+, then drop H2O off and leaves + charge on the ring. H on the carbon with methyl group is easier to drop off, and give you the double bond on pos...
