1. Perform a STEEP analysis to understand the general environment facing Great Lakes. How will Great Lakes be affected by external factors? 2. Use Porter’s Five Forces Model to analyze the lead additives industry in the US. Given this analysis‚ is the industry attractive or unattractive? 3. Using the 3I’s framework determine Great Lakes’ immediate‚ impending and invisible competitors. How does Great Lakes measure up against these competitors? 4. What are the main capabilities

Title: Experiment 28: Nitration of Methyl Benzoate Objective: The students will learn to nitrate methyl benzoate through electrophilic aromatic substitution reaction. They will learn the importance of regiochemistry in chemical reactions. They might experience disubstitution through a high temperature. Reactions: Observation: The crystals started to form when added 2 g of crushed ice. The addition of hot methanol dissociated the crystals. The crystals reappeared when cooled down in

"CHEMISTRY REVIEW" PROJECT PAGES This Project Page first appeared in the November 1996 issue of Chemistry Review‚ Volume 6‚ Number 2‚ Pages 14 and 15. Chemistry Review is published four times during the academic year by Philip Allan Updates and is a journal for post-16 students. It contains a variety of interesting and colourful articles aimed at 16-19 year-olds taking mainly AS and A2 courses in chemistry. NOTE: Project Page is designed to help you think about your investigation. It is not

The reaction of 0.139 grams of trans-cinnamic acid‚ 0.8 mL of glacial acetic acid‚ and 1.0 mL of 1.0 M of Bromine in acetic acid was recrystallized to form a solid‚ clear‚ crystal- like product. The melting was taken from the recrystallized product to determine what had been obtained. The melting point was found to be 130.5°C-133.7°C. Concluding that the product formed from the addition of bromine was a mixture of the erythro-2‚ 3-dibromo-3-phenylpropanoic acid‚ which has a known melting point of 204°C
