Chapter 2, Problem 44QAP
Interpretation Introduction
Interpretation: The measurement or calculation with one significant figure should be determined.
Concept Introduction: For writing significant figures, following rules should be followed:
- Every non-zero digits are significant. For example, the number 2356 has 4 significant figures.
- Any zero between two non-zero digits are significant. For example, the number 205 has 3 significant figures.
- The trailing zeros after the decimal are significant. For example, 0.450 has 3 significant figures, 100 has 1 significant figure and 0.025 has 2 significnat figures.

8. (16 pts) Provide the stepwise mechanism for the synthesis of the following compound via an enamine
Draw the titration curve of (i) weak acid vs. strong base; (ii) weak acid vs. weakbase; (iii) diprotic acid with strong base (iii) triprotic acid with strong base.
Complete the reaction in the drawing area below by adding the major products to the right-hand side.
If there won't be any products, because nothing will happen under these reaction conditions, check the box under the drawing area instead.
Note: if the products contain one or more pairs of enantiomers, don't worry about drawing each enantiomer with dash and wedge bonds. Just draw one molecule
to represent each pair of enantiomers, using line bonds at the chiral center.
