Textbook Question
Chapter 11, Problem 11.46P
Tautomerization in base resembles tautomerization in acid, but deprotonation precedes protonation in the two-step mechanism. (a) Draw a stepwise mechanism for the following tautomeization. (b) Then draw a stepwise mechanism for the reverse reaction, the conversion of the keto form to the enol.

Reagan is doing an atomic absorption experiment that requires a set of zinc standards in the 0.4-
1.6 ppm range. A 1000 ppm Zn solution was prepared by dissolving the necessary amount of
solid Zn(NO3)2 in water. The standards can be prepared by diluting the 1000 ppm Zn solution.
Table 1 shows one possible set of serial dilutions (stepwise dilution of a solution) that Reagan
could perform to make the necessary standards. Solution A was prepared by diluting 5.00 ml of
the 1000 ppm Zn standard to 50.00 ml. Solutions C-E are called "calibration standards" because
they will be used to calibrate the atomic absorption spectrometer.
