Answer:
We will not have a reaction.
Explanation:
The alcohol 2-methylhexan-2-ol its a tertiary alcohol. Additionally, the reaction of [tex]K_2Cr_2O_7[/tex] and acid medium will produce chromic acid [tex]H_2Cr_2O_7[/tex] with the following reaction:
[tex]K_2Cr_2O_7~+~2H^+->~H_2Cr_2O_7~+~2K^+[/tex]
Chromic acid is a strong oxidant, so an oxidation-reduction reaction will take place. But, in this case. we have tertiary alcohol (see figure 1). Primary alcohols are oxidized to aldehydes and aldehydes are oxidized to carboxylic acids. Secondary alcohols are oxidized to ketones and tertiary alcohols can not be oxidized due to the lack of hydrogens on the carbon that is bonded to the "OH" group.
Therefore we will have no reaction.
I hope it helps!
