Cyclohexanol is heated with aluminium tert-butoxide in excess propanone. This Oppenauer oxidation gives

Ahexanedioic acid
Bcyclohexene
Ccyclohexane
Dcyclohexanone

Answer: D

Oppenauer oxidation is the reverse of MPV reduction: a secondary alcohol is oxidised to a ketone by hydride transfer to the excess propanone. Cyclohexanol gives cyclohexanone, not an acid.
