Alcohols undergo an oxidation reaction to yield carbonyl compounds on treatment with $mathrm{CrO}_{3}$. For example, 2 -tert-butylcyclohexanol gives 2 -tert-butylcyclohexanone. If axial -OH groups are generally more reactive than their equatorial isomers, which do you think reacts faster, the cis isomer of 2-tert-butylcyclohexanol or the trans isomer? Explain.
