- C28H37N10O23P3 How do you draw this structure?In this organic nomenclature, what does the (4E), "en" and "yl" mean?A student adds bromine solution to a test tube containing an isomer of C3H6. After shaking the sample and exposing it to UV light, the student observes that the colour of the bromine solution changes from orange to clear. Provide a hypothesis for what happened in the test tube. What do you believe to be the structure of the original isomer, and what was the final product, if a reaction occurred?
- An isomer of C6H12O could contain a carboxylic acid. True or false?Cd(s) + MgBr2(aq) →(5) One of Prof Cunningham's former students wrote his doctoral dissertation about a new technology to clean up soil contaminated by certain types of chemicals. One of the chemicals we tested in the lab was 1,2,4,5-tetrachlorobenzene (TECB). (a) Draw the chemical structure of 1,2,4,5-tetrachlorobenzene. (b) When we started working on the project, we thought maybe TeCB would be de- stroyed according to first-order kinetics, but we weren't sure. Below are two tables of actual data that the student collected in the laboratory. The two data sets were collected under different experimental conditions. For each of the two experiments, determine if the disappearance of TeCB is zero-order, first-order, second-order, or something else. Specify the value of the rate constant (ko, k1, or k2, as appropriate). Be sure to give the right units of k! Table 1: Concentration of TECB vs. time, experiment 1 time (min) Conc.
