Consider the following compounds that vary from nearly nonacidic to strongly acidic. Draw the conjugate bases of these compounds, and explain why the acidity increases so dramatically with substitution by nitro groups.CH4 CH3NO2 CH2(NO2)2 CH(NO2)3 pKa ≅ 50 pKa = 10.2 pKa = 3.6 pKa = 0.17
Calculate the pKa of each acid and indicate which is the stronger acid.
C6O2H8, Ka = 1.7 x 10–5
C2O4H2, Ka = 5.9 x 10–2
Dicarboxylic acids have two pKa's.- For maleic acid (cis-2-butenedioic acid) these are pKa1 = 2.0, and pKa2 = 6.3- For fumaric acid (trans-2-butenedioic acid) these are pKa1 = 3.0, and pKa2 = 4.5
Which factor best explains why the cis-isomer has a smaller pKa1 and a larger pKa2 than the trans-isomer?
a.
Intramolecular hydrogen bonding
b.
Intramolecular steric hindrance
c.
Selective solvation in water
d.
Intramolecular dipole repulsion
