Substitution occurs more readily when a halide ion (eg cl from HCI) is present, resulting in the -OH group of the alcohol being replaced by a halogen atom. A strong acid is necessary, since the H* converts the -OH group into - OH2*, which can then be lost as a water molecule: CH3 H2C=C elimination CHą -H,,! CH3 CH3 CH3 CH3 H3C-Ć-OH H3C-Ć-ÖH2 + H2O + H3C-c@ сна CH? CH3 2-methyl-2-propanol C H3C-C-Cl a 3° carbocation substitution CH3 2-chloro-2-methylpropane Carbocations...
