6.4. Acid strength and pKa Organic Chemistry 1: An open textbook
WebAug 26, 2024 · The acetate ion is more stable than the phenoxide ion, so we would expect acetic acid to be the stronger acid. The pKa table below supports our prediction. Acetic acid has a pKa of 4.7 while phenol has a pKa of 9.9. A word of caution: when using the pK a table, be absolutely sure that you are considering the correct conjugate acid/base pair. WebJan 28, 2024 · Notice that the pK a -lowering effect of each chlorine atom, while significant, is not as dramatic as the delocalizing resonance effect illustrated by the difference in pK a values between an alcohol and a carboxylic acid. In general, resonance effects are more powerful than inductive effects. WebJun 18, 2010 · The reaction that happens is the simplest one – deprotonation of SH, to provide water and the deprotonated thiol. Also, the pK a table tells you about leaving group ability. Good leaving groups are weak bases! If you don’t know the relative values of the pK a ‘s of the major functional groups, you’ll be flying blind in the course. sunsetsecuritydfw.com
