- 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.arrow_forwardExplain why m-nitroaniline is a stronger base than p-nitroaniline.arrow_forwardPhenol 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-hyroxybenzaldehydearrow_forward
- НО. meta-Hydroxyacetophenone HO para-Hydroxyacetophenone The conjugate base of the para isomer has a negative charge that is delocalized over atom(s), and the conjugate base of the meta isomer has a negative charge that is delocalized over oxygen atom(s). Therefore, the conjugate base of the meta isomer is carbon atom(s) and isomer, making meta-hydroxyacetophenone oxygen carbon atom(s) and stable than then conjugate base of the para ✓acidic than para-hydroxyacetophenone.arrow_forwardRank the nitrogen atoms in each compound in order of increasing basicity.
