Vedclass · Answer

(B) The dehydration of cyclohexanol to cyclohexene is an elimination reaction ($E1$ mechanism). Concentrated phosphoric acid $(H_3PO_4)$ is the preferred reagent for this dehydration because it is a non-oxidizing acid and minimizes side reactions like oxidation or substitution compared to concentrated sulfuric acid or hydrohalic acids. Thus,heating cyclohexanol with concentrated $H_3PO_4$ yields cyclohexene efficiently.
