Students have asked these similar questions
You are planning to carry out a reaction that produces protons. The reaction will be buffered at pH = 10.5. Would it be better to use a protonated methylamine/methylamine buffer or a protonated ethylamine/ethylamine buffer? (pKa of protonated methylamine = 10.7; pKa of protonated ethylamine = 11.0)
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.
hydrogens 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.
