- Define why are protons on an alpha carbon of an aldehyde or ketone more acidic than a proton on an alpha carbon of an ester? What are their pKa's?The C-H bond in acetone, (CH3)C=O, has a pką of 19.2. Draw two resonance structures for its conjugate base. Then, explain why acetone is much more acidic than propane, CH;CH,CH3 (pKa = 50). %3Dh) Which is a weaker base and why? Pyridine Pyrrole i) Name the following compounds. H2N A B NH2
- Using pKa Values to Determine Relative Acidity and Basicity Rank the following compounds in order of increasing acidity, and then rank their conjugate bases in order of increasing basicity.4-Methylphenol is more acidic than ethanol (pKa 10.36 vs 16.0) , even though both contain an OH group and a methyl group. Draw the structures of the anions formed from loss of the alcoholic protons from both compounds. Use resonance to explain the difference in their respective acidities.Phenol has a pka = 10.0. 4-Hydroxybenzaldehyde has a pka = 7.3. Draw resonance forms of the conjugate base of both and explain why 4-hydroxybenzaldehyde is more acidic. (Acidic H is underlined.) OH phenol OH -H* - H* 4-hyroxybenzaldehyde

Нас — ОН ОН H3C- ОН OH pKa = 15.5 pKa = 10.0 pk = 4.75 pk = 4.2hydrogens on a carbon adjacent to a carbonyl group are far more acidic than those not adjacent to a carbonyl group. The anion derived from acetone, for example, is more stable than is the anion derived from ethane. Account for the greater stability of the anion from acetone.

OH но -COOH -соон p-hydroxybenzoic acid o-hydroxybenzoic acidAmphetamine is a powerful stimulant of the central nervous system.Draw the products formed (and show the flow of electrons) from the acid-base reaction of amphetamine with (a) HCl and with (b) NaH.Ketones typically have a pka of approximately 20. While this is certainly not a strong acid it is much stronger than a typical alkane sp3-CH. using acetone as an example, explain why ketones are much more acidic than Alkanes.
