12.8 A student is following a reaction (the conversion of compound A to Com- pound B) by TLC. Aliquots of the reaction mixture are taken and analyzed at time = 0, 10, 20, and 30 min. The TLC plate, developed in 90% hexanes-10% ethyl acetate, is shown below. (a) Which is the more polar compound, A or B? (b) Is the reaction complete at 10 min? 20 min? 30 min? (c) How can the identity of Compound B be verified by TLC? Compound A origin ● 0 10 20 30 Compound B

2. The fluorenone reduction reaction ran for 3 minutes. A TLC was done to monitor the progression of the reaction. According to the TLC, the product started to form at 30 seconds and completed forming at 2 minutes. Sketch a TLC plate monitoring the progression of this reaction for the duration of 3 minutes (interval at 0 sec., 15 sec., 30sec., 60 sec., 120 sec., 180 sec.).
[3] Instructions: Read each excerpt from a research paper and identify the dependent, independent, controlled variable (at least 1), experimental group/treatment, and control group. Antibacterial Assay The test solution of each extract was prepared by dissolving 0.1g of the plant extract separately. 1.0cm3 of dimethyl sulphoxide (DMSO) to get a concentration of 100mg/cm3. The antibacterial activity was performed by filter paper disc diffusion technique. Filter paper disc (Whatman No 1.6 mm diameter) were placed in glass Petri dish and sterilized in a hot air oven. Iwu et al 2018b, the media (10g nutrient Agar in 200cm3 distilled water, autoclaved at 115°C for 30 minutes) was cooled to 50°C. The sterile nutrient Agar media were poured into the sterile Petri dish and allowed to solidify. The bacteria were swabbed with a sterile wire loop. Each disc was impregnated with 0.2cm3 of plant extract. Standard antibiotic Ciprofloxacin was used as a control on a disc with DMSO 100 mg/cm3. The…

A reaction mixture spotted on the TLC plate has been refluxing for one hour. There is a single organic product of the reaction. After 1 hour a student elutes a TLC plate of the starting material(s) (SM), the known product (P) and the reaction mixture (RM). Based on the TLC below, do you think the reaction should be refluxed further? Explain your answer. SM+ P + RM+ O O O
