Organic Chemistry- Oxidation of Primary, Secondary, Tertiary Alcohols

Oxidation of Primary, Secondary, Tertiary Alcohols

Description: Samples of alcohols are added to acidic dichromate solutions, which are orange. The rate at which orange color converts to blue chromium (III) is compared for the three types of alcohols.
