Alkenes (water removed from alcohol)

Alkyl halides ($\text{-OH}$ replaced by halogen)

Conc. $\text{H}_2\text{SO}_4$ or $\text{H}_3\text{PO}_4$

Heated $\text{Al}_2\text{O}_3$ (aluminium oxide)

$\text{R-OH} + \text{HX} \to \text{R-X} + \text{H}_2\text{O}$

One other carbon

Two other carbons

Three other carbons
