Classification of Alcohols 1°, 2°, 3 °­ carbon bonded to alcohol bonded to 1 carbon, 2  carbons, or 3 carbons 3. Reactions of alcohols and Thiols A. Oxidation/Reduction­  1°, oxidize an alcohol an aldehyde, then a carboxylic acid  2°, oxidized then is a ketone  2 thiols­ becomes a disulfide bond­ loss of oxygen  B. Dehydration­ take out a water, with addition of H+ and heat, has to bsecondary  alcohol  12.5 Properties of Aldehydes and Ketones Physical Properties • The polar carbonyl group provides dipole­dipole interactions.         d+    d­     d+    d­ C=O              C=O • Because the electronegative oxygen atom forms hydrogen bonds with water molecules, aldehydes and  ketones with one to four carbons are very soluble. • The electronegative O atom of the carbonyl group of aldehydes and ketones forms hydrogen bonds  with water.  AgNO3+          Ag  + Benedict’s Test 2+   • In Benedict’s test, Benedict’s reagent, which contains Cu ,reacts with aldehydes that have an  adjacent OH group. • An aldehyde is oxidi
