QUESTION 3 4points Save Answer The catalyst is re-generated in the dehydration reaction of an alcohol to catalyst? prepare an alkene. Which of the tolowing statements describes the process of re-generation of the Heat re-generates the catalyst Elimination involves bond breakage and re-generates the catalyst A weak base, e.g, the bisulfate ion (HSO4) abstracts a proton and re-generates the catalyst Protonation of the alcohol converts the very poor leaving group,-OH, into a much betfer leaving group, water, and re-generates the catayat

Explanation / Answer

Ans : Protonation of alcohol converts the very poor leaving group , -OH , into a much better leaving group , water , and regenerates the catalyst.

The dehydration reaction of alcohol to form alkene takes place in three steps.

The first step observes the protonation of alcohol . In the second step , the protonated alcohol loses water to form a carbocation and this carbocation loses proton to regenerate the catalyst back.
