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.
