When an alcohol is treated with sodium hydroxide, the following acid-base equilibrium occurs. The primary alcohols follow the E2 mechanism for elimination reaction while the E1 mechanism is followed by secondary and tertiary alcohols.

You might ask: if we treat a primary alcohol (say, 1-butanol) with a strong acid like H2SO4, will also get elimination to an alkene? R–O–H + Na (+) OH (–) R–O (–) Na (+) + H–OH. The formation of protonated alcohol; The formation of carbonation The elimination of water from an alcohol is called dehydration. Here’s an example. Most alcohols are slightly weaker acids than water, so the left side is favored. Normally, it is a three-step mechanism. What About Primary Alcohols?

Alcohol elimination reactionsoccur when an alcohol reacts with an acid. An alcohol is a carbon with an OH group attached. Primary alcohols undergo bimolecular elimination (E2 mechanism) while secondary and tertiary alcohols undergo unimolecular elimination (E1 mechanism). The alcohol can be primary (the carbon is only attached to one other carbon atom and two hydrogen atoms), secondary (the carbon is attached to two other carbon atoms and one hydrogen atom), or tertiary(the carbon is attached to three other carbon atoms and no hydrogen atoms). The steps are explained as follows. The relative reactivity of alcohols in dehydration reaction is ranked as the following Methanol < primary < secondary < tertiary Primary alcohol dehydrates through the E2 mechanism. 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. Acids such as hydrochloric acid do no… Recalling that water is a much better leaving group than hydroxide ion, it is sensible to use acid-catalysis rather … The dehydration of alcohol follows the E1 or E2 mechanism. Yes, alkenes can be formed this way (along with some formation of symmetrical ethers. The acid needs to be phosphoric acid, sulfuric acid, or tosic acid. The final class of alcohols to be concerned about is primary alcohols.
