Given E2 reactions are to be ranked in the order of their increasing rate. Concept introduction: The relative rates of E2 reactions depend on the strength of the base and the leaving group ability. The more stable leaving group has better leaving group ability. The rate of an E2 reaction generally increases as the strength of the base increases (i.e., as the pK a of the base’s conjugate acid increases). Strong bases tend to favor E2 reactions.

Interpretation Introduction

Interpretation:

Given E2 reactions are to be ranked in the order of their increasing rate.

Concept introduction:

The relative rates of E2 reactions depend on the strength of the base and the leaving group ability. The more stable leaving group has better leaving group ability. The rate of an E2 reaction generally increases as the strength of the base increases (i.e., as the pKa of the base’s conjugate acid increases). Strong bases tend to favor E2 reactions.

On the next page is an LC separation of the parabens found in baby wash. Parabens are suspected in a link to breast cancer therefore an accurate way to quantitate them is desired. a. In the chromatogram, estimate k' for ethyl paraben. Clearly indicate what values you used for all the terms in your calculation. b. Is this a "good" value for a capacity factor? Explain. c. What is the resolution between n-Propyl paraben and n-Butyl paraben? Again, indicate clearly what values you used in your calculation.

d. In Figure 4, each stationary phase shows some negative correlation between plate count and retention factor. In other words, as k' increases, N decreases. Explain this relationship between k' and N. Plate Count (N) 4000 3500 2500 2000 1500 1000 Figure 4. Column efficiency (N) vs retention factor (k') for 22 nonionizable solutes on FMS (red), PGC (black), and COZ (green). 3000 Eluent compositions (acetonitrile/water, A/W) were adjusted to obtain k' less than 15, which was achieved for most solutes as follows: FMS (30/70 A/W), PGC (60/40), COZ (80/20). Slightly different compositions were used for the most highly retained solutes. All columns were 50 mm × 4.6 mm id and packed with 5 um particles, except for COZ, which was packed with 3 um particles.
