Question
Which is the best reagent to convert cyclohexanol into cyclohexene?
✓

Answer

Cyclohexanol is used as substrate and phosphoric acid is present as catalyst which promotes the reaction but is not consumed in it. The hydroxyl group in $\ce{R-OH}$ is a poor leaving group because it leaves as hydroxide ion. An acid is used to protonate the alcohol and form $\text{R}−\text{OH}_2^+​$
