WebOxidation of Alcohols. In organic chemistry, the oxidation of alcohol is a crucial reaction. Aldehydes and carboxylic acids are formed when primary alcohols are oxidised; ketones are formed when secondary alcohols are oxidised. Tertiary alcohols, on the other hand, cannot be oxidised without breaking the C–C bonds in the molecule. 1. alcohols: C 2 H 4 (OH) 2: Ethane-1,2-diol Ethylene glycol: C 3 H 6 (OH) 2: Propane-1,2-diol Propylene glycol: C 3 H 5 (OH) 3: Propane-1,2,3-triol Glycerol: C 4 H 6 (OH) 4: Butane-1,2,3,4-tetraol Erythritol, Threitol: C 5 H 7 (OH) 5: Pentane-1,2,3,4,5-pentol Xylitol: C 6 H 8 (OH) 6: hexane … Meer weergeven In chemistry, an alcohol is a type of organic compound that carries at least one hydroxyl (−OH) functional group bound to a saturated carbon atom.
