Alcohols

Alcohols can be oxidized by using chemicals like acidified potassium dichromate in warm conditions The products vary depending on the type of alcohol For example - a primary alcohol will oxidize to to an aldehyde and given further oxidation it will become a carboxylic acid Have a look at the examples below using ethanol

Oxidation of alcohols

Because the solution is alkaline the aldehyde itself is oxidised to a salt of the corresponding carboxylic acid If we are wanting to oxidise a primary alcohol all the way to a carboxylic acid then it is important to make sure than the aldehyde does not escape before it is

Oxidation of Alcohols: PCC CrO3 DMP

Oxidation of an Alcohol with Chromic Acid (H 2 CrO 4) Aqueous acidic solutions of sodium dichromate (Na 2 Cr 2 O 7) or chromium trioxide (CrO 3) are used to form chromic acid (H 2 CrO 4) which oxidizes primary and secondary alcohols to carboxylic acids and secondary alcohols to ketones respectively:

Alcohol oxidation

Alcohol oxidation is an important organic reaction Primary alcohols (R-CH 2-OH) can be oxidized either to aldehydes (R-CHO) or to carboxylic acids (R-CO 2 H) while the oxidation of secondary alcohols (R 1 R 2 CH-OH) normally terminates at the ketone (R 1 R 2 C=O) stage Tertiary alcohols (R 1 R 2 R 3 C-OH) are resistant to oxidation The indirect oxidation of primary alcohols to carboxylic
