NafeQureshi Date: 06/22/09 T.A: Joe Azzarella ExP:07(OXIDATION OF ALCOHOLS: PREPARATION OF CAMPHOR) Introduction: Purpose of this experiment Oxidation of a secondary alcohol, isoborneol to a ketone,camphor. Oxidation in organic chemistry is defined as either (a) loss of hydrogen atoms or (b) addition of bonds to oxygen or other atoms more electronegative than carbon. Oxidation of alcohols provides a general method for the preparation of carbonyl compounds. Oxidation of primary alcohols produces aldehydes or carboxylic acids depending on the oxidizing conditions. Oxidation of secondary alcohols produces ketones while tertiary alcohols cannot be oxidized without breaking carbon-carbon bonds. The most common oxidizing agents for the conversion of alcohols to aldehydes and ketones are chromium trioxide (CrO 3 ), the chromate ion (CrO 4 -2 ) and the dichromate ion (Cr 2 O 7 -2 ). When these oxidizing agents are used in aqueous solution, the product obtained from primary alcohols is a carboxylic acid. Modified forms of CrO 3
