The substituents present at 1 and 2 positions of a chair cyclohexane take an axial and an equatorial position in cis form, but both equatorial positions or both axial positions in the trans form Hence, the axial B r has an adjacent axial hydrogen at C 2 and (C 6) in cis form but only at C6 in trans Therefore, the former can give the more substituted 1 but the latter cannot For example, trans2methyl1chlorocyclohexane reacts with alcoholic KOH at a much slower rate than does its cisisomer Furthermore, the product from elimination of the transisomer is 3methylcyclohexene (not predicted by the Zaitsev rule), whereas the cisisomer gives the predicted 1methylcyclohexene as the chief product These differences E1 elimination of 1bromo1methylcylclohexane using KOtBu?
