WebThe oxidation of primary alcohols is a common method for the synthesis of carboxylic acids: RCH 2 OH → RCOOH. This requires a strong oxidizing agent, the most common being chromic acid (H 2 CrO 4 ), potassium permanganate (KMnO 4 ), and nitric acid (HNO 3 ). Aldehydes are oxidized to carboxylic acids more easily (by many oxidizing agents ... WebThe molecule with the two OH groups is usually ethane-1,2-diol: HOCH 2 CH 2 OH. Molecules like this are often called diols - that just means two OH groups. Benzene-1,4-dicarboxylic acid (old name: terephthalic acid) is frequently used as the molecule with two COOH groups.
