Roadmaps and Predicting Products

Many Organic Chemistry II exams contain problems known as roadmaps that present you with a collection of facts you use to deduce the identities of a number of compounds. 

Over the years, we have seen numerous students throw up their hands when faced with a roadmap problem. Indeed, many students simply skip the roadmap problems on their exams. That s a good way to lose a significant number of points and unnecessarily lower your grade. 

If you know your reactions and the other rules, roadmaps aren t as difficult as they seem. The secret is to tackle the problem in small pieces, first by reading the problem and making a few notes then continuing with the exam. Come back to the problem later and make a few more notes. Then go to some other part of the exam. Continue cycling from the roadmap to other questions on the exam until you have sufficient notes to attempt to solve the roadmap. 

If the roadmap defies solution at this point, return to the cycling procedure until you re ready to make another attempt or until that s the only part left on the exam. 

Now you get to take a look at number of roadmap problems. Some instructors include spectra on one or more of the compounds in the problem. We limit the amount of spectral data so you can focus on the approach to the solution of roadmap problems.

If a fuel gas balance model predicts that the plant will be in fuel gas long, a solution roadmap detailing what the plant can do in the short and long term should be developed. Efforts to reduce fuel gas production must attempt to understand the root causes and determine the best choice for reducing it via both operational changes and capital projects. 

Japanese companies are ahead of the rest of the world in the introduction of lead-free products. The Japan Institute of Electronics Packaging s Technology Roadmap for Electronics Packaging in 2010 documents the path toward lead-free product introduction. Lead-free component production is noted to have started in 2000 with rapid progress anticipated between 2003 and 2005. The use of lead-free solder is expected to become pervasive in Japan. While there are a number of products with lead-free solder today, many additional products are expected. The roadmap predicts that the use of lead-free solder will surpass conventional lead-based solders by 2003. While conventional lead-based solders will still be utilized until at least 2010, the volume is...
