Question

The catalyst is re-generated in the dehydration reaction of an alcohol to prepare an alkene. Which of the following statements describes the process of re-generation of 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 better leaving group, water, and re-generates the catalyst

Heat re-generates the catalyst  

Elimination involves bond breakage and re-generates the catalyst

Explanation / Answer

The catalyst is re-generated in the dehydration reaction of an alcohol to prepare an alkene. Which of the following statements describes the process of re-generation of the catalyst?

Regeneration of catalyst involves the abstraction of proton by a weak base

Answer is first option: A weak base, e.g. the bisulfate ion (HSO4-) abstracts a proton and re-generates the catalyst
