Chapter B, Problem B.7P
Interpretation Introduction

(a)

Interpretation:

The IUPAC name for the given compound is to be determined.

Concept introduction:

For a molecule that has more than one double bond or triple bond, the IUPAC name must indicate the number of double bonds or triple bonds present as well as their locations. To name the molecule with multiple double/triple bonds, establish the root as the longest carbon chain or the largest carbon ring that contains the greatest number of entire C=C or CC groups. Number the chain or ring so that each successive C=C or CC group is encountered the earliest. For each pair of C=C or CC atoms, identify the lower of the two locator numbers. Immediately before the ene or yne suffix, add the letter ‘a’ followed by the above set of locator numbers, and then add the prefix di, tri, etc. to specify the number of double or triple bonds. The substituents attached to the root are named in the alphabetical order.

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. All other chromatographic conditions were constant: column length 5 cm, column j.§. 4.6 mm, flow rate 2 mL/min, column temperature 40 °C, and injection volume 0.5 μL Log(k'x/K'ethylbenzene) FMS 1.5 1.0 0.5 0.0 ཐྭ ཋ ཤྩ བྷྲ ; 500 0 5 10…
