Document Summary
Ch 19. 5e,c,d, 19. 8b-19. 9a: preview, how to make carboxylic acids a. i. Oxidation of aldehydes: nomenclature and properties of carboxylic acids, naming a. i. E is dropped and oic acid is added: polarity b. i. With 5 carbons or less is soluble in water: salt c. i. Combo of carboxylate anion with metal ion c. ii. Naming is instead of oic acid it is ate c. ii. 1. Benzoate: structure, sp2 carbons, planar, 2 hydrogen bonds, 2 energy minima = s-cis and s-trans c. i. Problem 17. 3 in aqueous solution, s-cis form more stable c. ii. Easy interconversion from s-cis to s-trans: nmr spectra of carboxylic acids, nmr a. i. H of cooh is most acidic h of typic functional groups: acidity and basicity of carboxylic acids, very acidic, more than alcohol, due to a. i. resonance of anion a. ii. polarity of carbonyl group, addition b. i. Base will have hard time adding to carbonyl group b. ii.
