29. What exactly is relative retention and retention time? How do you solve problems like this?
6.0 mL of cyclohexanol, 8 mL of 85% phosphoric acid, and 10 drops of sulfuric acid are added to a 50-mL round-bottom flask with boiling chips, and the mixture is distilled into an ice-cooled receiver. The distillate is in the form of a colorless bi-phasic mixture. The cyclohexene upper layer is removed from the water layer, and dried over anhydrous calcium chloride. Isolated is cyclohexene as a clear and colorless foul-smelling liquid. Weighing data is given below. Gross mass: 51.24 g Tare mass: 48.04 g Product mass: 3.2g Question: Calculate the theoretical mass of the cyclohexene product, bearing in mind that the cyclohexanol starting material was measured by volume, not by mass (so you must use the density of cyclohexanol to convert milliliters to grams, before calculating the number of moles). Calculate the percent yield of cyclohexene obtained.
What would happen to the retention time of a given compound if the carrier gas flow rate of the gas chromatograph is increased? The retention time would increase. The retention time would decrease. The retention time would not change.
The figure below shows a typical separation of several fat-soluble vitamins by HPLC. The x-axis is retention time in minutes. From the graph try to estimate retention times for peaks 2 and 3. Retention time peak 2 = Retention time peak 3 = Assume that w1/2 is 0.15 minutes for peak 2 and 0.16 minutes for peak 3. Assume that tm is 2.00 minutes. How much time does gamma-tocopherol spend in the stationary phase? From tr and w1/2 find N for the peak that elutes first. From tr and w1/2 find the resolution of peaks 2 and 3 Calculate α for these peaks. If the flow rate for the column is 1.2 mL/minute what is the retention volume for peak 4?
Identify the 6 parameters used when quantifying toxic organic compounds.
I'm working on a pre-lab report for chemistry regarding retention factors. The question asks what is the maximum distance the indicator band will travel? Is the indicator band sometimes referred to as the indictor spot?

A sample of explosives residue is dissolved in an appropriate solvent and is injected into HPLC. The column contains a non- polar stationary phase. The sample revealed three chemical compounds that are commonly present in homemade explosives. ТAТP DADP HMTD 1 2 3 4 5 6 7 8 Retention time (minutes) a) determine the retention time of TATP. b) which one elute first :DADP,TATP or HMTD? c) State and explain which compound is most polar. d) If you are investigating this terrorist attacks, state one way in which the information in the chromatogram would be useful.
If the stationary phase and the compound being tested are both polar, will the retention factor (Rf) likely be smaller or larger than if a nonpolar compound was tested? Why? 1) The retention factor will likely be smaller as it has a smaller interaction with the stationary phase O 2) The retention factor will likely be greater as it has a smaller interaction with the stationary phase O3) The retention factor will likely be smaller as it has a greater interaction with the stationary phase 4) The retention factor will likely be greater as it has a greater interaction with the stationary phase
