Since water is “removed”

Reactions of Alcohols - Rutgers University
crab.rutgers.eduThe first step is the exothermic protonation of the hydroxyl, followed by the slow, endothermic, rate determining ionization to generate the cation. The fast deprotonation is exothermic and produces the alkene. Since the RDS is the formation of the carbocation, the ease of formation dictates the reaction rates of 3° > 2° > 1°.
REACTIONS OF ALCOHOLS
www.ntci.on.ca6. Acid-Base Reactions • Like water, alcohols can act as an acid or base, depending on what it is reacting with. • When they react as an acid, the alkyl oxide ion (R-CH2O-) is formed. ethanol + sodium ethoxide ion + sodium ion + hydrogen 2 CH3CH2OH + 2 Na 2 CH3CH2O-+ 2 Na+ + H2
