1. (4 pts) Rate the
following entities as Lewis acids (A), Lewis bases (B),
or neither (N); do this by placing the appropriate letter (A,
B, or N) on the line under the species.
2. (4 pts) The following questions will use the table below of several compounds and their pKa values
|
b. Draw the conjugate base of the least acidic molecule, showing resonance structures if appropriate:
|
c. Rounding off the pKa values for phenol (to 10) and CH3CH2OH (to 16), which of these is the stronger acid? How many times more acidic is it than the weaker acid?
3. (2 pts) For the six molecules/ions below, decide whether each one is planar (P), nonpolar (N), or neither. Then, designate the planar/nonpolar entities by placing the letters P and/or N on the line below the species. In other words, the line below each molecule might have one letter, two letters, or none.
