Estimate the pKa of protonated phenol and protonated aniline (shown below). State which of the molecules is a stronger acid. Related to exercise 3: Relative Basicity of Oxygen and Nitrogen Atoms in 4-Aminophenol and Formamide 5) Estimate the pKa of protonated phenol and protonated aniline (shown below). State which of the molecules is a stronger acid.
The Ricci equation is often used to estimate pKa values of oxoacids. The equation is: pKa = 8 - 9f + 4(n-m) for an acid with the formula HmXOn, with f = formal charge on X IF ALL OXYGEN ATOMS MAKE SINGLE BONDS TO X. Use the Ricci equation to estimate the pKa of each of the following acids: H2SeO4, H2SeO3, HSeO3-, HNO3, H3BO3.
List two classes of compounds (by class I mean molecules that contain a like functional group) that are incompatible (in other words destroys the Grignard) with the Grignard reagent.
Interactive Case Study # 2 Henderson Hasselbach Relationship Can you help me find the correct pKa for each compound, and explain which one is the right answer? (d) Gaba, an important neurotransmitter in the human brain, is represented in different ionization states below. Circle the most dominant form of this compound at pH-7. Show work to justify how you arrived at this answer. To help, a generic pKa table has been provided on the next page but these values can...

Explain why amino acid functional groups that participate in acid-base chemistry have perturbed pKa values from simple methyl substituted amino and carboxyl groups. (3 points) Explain why amino acid functional groups that participate in acid-base chemistry have perturbed pKa values from simple methyl substituted amino and carboxyl groups. (3 points)
From your plot, estimate the pKa values for the a-COOH and a-NH3+ groups of Gly. Use arrows to indicate these pKa values on the curve: pH vs. Accumulated Equivalents of NaOH 12 10 6 2 2 4 6 10 12 Accumulated Equivalents of NaOH (mL) O Hd pH vs. Accumulated Equivalents of NaOH 12 10 6 2 2 4 6 10 12 Accumulated Equivalents of NaOH (mL) O Hd
