5.2: Acid Strength and pKa - Chemistry LibreTexts
WebA series of novel cannabinoid-type derivatives were synthesized by the coupling of (1S,4R)-(+) and (1R,4S)-(−)-fenchones with various resorcinols/phenols. The fenchone-resorcinol derivatives were fluorinated using Selectfluor and demethylated using sodium ethanethiolate in dimethylformamide (DMF). The absolute configurations of four … WebLooking at Table 5.2. 1, you see that the pK a of carboxylic acids are in the 4-5 range, the pK a of sulfuric acid is –10, and the pK a of water is 14. Alkenes and alkanes, which are not acidic at all, have pK a values above 30. The lower the pKa value, the stronger the acid.
