Compare and contrast the major products of dehydrohalogenation of 2-chloro-4-methylpentane with
(a) Sodium ethoxide in ethanol and
(b) Potassium tert-butoxide in 2-methyl-2-propanol (tert-butyl alcohol).
Write the mechanism of each process. Next consider the reaction of 4-methyl-2-pentanol with concentrated H2S04 at 130°C and compare its product(s) and the mechanism of its (their) formation with those from the de-hydro-halogenations in (a) and (b).
