Dehydration of alcohols order
WebThe order of dehydration among three type of alcohols is 3^ {\circ} > 2^ {\circ} > 1^ {\circ} > CH_ {3}OH 3∘ > 2∘ > 1∘ > C H 3OH. This behaviour is related to the relative stabilities of carbocations \left (3^ {\circ} > 2^ {\circ} > 1^ {\circ} \right) (3∘ > 2∘ > 1∘). Download Solution in PDF. Was this answer helpful? WebA dehydration reaction is a form of chemical reaction in which water is formed from the extraction of the components of water from a single reactant. When dehydration of alcohol is performed, an alkene is formed. The structural equation of alcohol dehydration is: C 2 H 5 OH → C 2 H 4 + H 2 O.
