The following problems are meant to be useful study tools for students involved in most undergraduate organic chemistry courses. The problems have been color-coded to indicate whether they are:. Generally useful2. Most likely to be useful to students in year long, rather than survey courses3. Some of these problems make use of a Molecular Editor drawing application.

Full discussions of the topics covered by these problems are available in the Virtual Textbook of Organic Chemistry. The following button will activate a random display of problems concerning the reactivity of common functional groups.
A large collection of multiple choice problems, similar to those used in standardized examinations, may be reached by clicking here. Comments, questions and errors should be sent to whreusch msu. Click on the name for information and a free copy. If possible, monitor resolutions of x or x should be used. The practice problems offered here are chiefly interactive, and should provide a useful assessment of understanding at various stages in the development of the subject.
Since problem solving is essential to achieving an effective mastery of the subject, it is recommended that many more problems be worked. Most organic chemistry textbooks contain a broad assortment of suitable problems, and paperback collections of practice problems are also available.

Then, things change, and I accumulate stuff. This page lists a range of things, all of which loosely are sets of practice problems, with some limited instructional material included in some cases. This page may be useful for people just browsing the web site looking for some practice.
Students in my current courses can access all problem sets from this page, but note that more complete information focused on the course may be available from the course page. Those who are using my web site materials for self-study You are welcome -- and encouraged -- to ask me questions when difficulties arise. My contact information is at the bottom of each of my web pages.
It always helps if you include how you would answer the question and why. That lets me respond to what you are thinking, lets me focus my reply on where you are having trouble. Further, it gives me a feel for the level at which you are addressing the question -- which may vary depending on your background and course level. The level of discourse -- and your learning of the subject matter -- is enhanced by trying to focus on reasons, not simply answers.
What is the difference between the various kinds of materials listed here, in the various sections? For each section, there is some general descriptive material.
However, I suggest visitors look at materials of different types, and decide what is suitable for their situation. A "quiz" can be used as a "worksheet", if that suits you -- or vice versa; both have problems to work and explanatory material, just in different arrangements.
Most of the homework for the chem classes is from the book.
However, in some cases, I provide small additional sets to supplement particular areas. Unless noted, these are distributed with the appropriate chapter handouts, and are also available here as PDF files.
They include answers. A small extra set with several questions, of a range of complexity, on a single reaction. The emphasis is that balanced equations give you the mole ratios between the chemicals in the reaction.A solution can vary in composition, while a compound cannot vary in composition. Solutions are homogeneous at the molecular level, while other mixtures are heterogeneous.
Solutions of hydrogen in palladium may be formed by exposing Pd metal to H 2 gas.

Under certain conditions, 0. Explain why solutions of HBr in benzene a nonpolar solvent are nonconductive, while solutions in water a polar solvent are conductive. Though HBr is soluble in benzene, it does not react chemically but remains dissolved as neutral HBr molecules. With no ions present in the benzene solution, it is electrically nonconductive. Therefore, z best represents the solution.
What is the expected electrical conductivity of the following solutions? Why are most solid ionic compounds electrically nonconductive, whereas aqueous solutions of ionic compounds are good conductors? Would you expect a liquid molten ionic compound to be electrically conductive or nonconductive? A medium must contain freely mobile, charged entities to be electrically conductive. The ions present in a typical ionic solid are immobilized in a crystalline lattice and so the solid is not able to support an electrical current.
When the ions are mobilized, either by melting the solid or dissolving it in water to dissociate the ions, current may flow and these forms of the ionic compound are conductive. Suppose you are presented with a clear solution of sodium thiosulfate, Na 2 S 2 O 3. How could you determine whether the solution is unsaturated, saturated, or supersaturated?
It will dissolve in an unsaturated solution, remain apparently unchanged in a saturated solution, or initiate precipitation in a supersaturated solution. It decreased as some of the CO 2 gas left the solution evidenced by effervescence. Opening the bottle released the high-pressure CO 2 gas above the beverage.
The dissolved CO 2 concentration will continue to slowly decrease until equilibrium is reestablished between the beverage and the very low CO 2 gas pressure in the opened bottle. Immediately after opening, the beverage, therefore, contains dissolved CO 2 at a concentration greater than its solubility, a nonequilibrium condition, and is said to be supersaturated.

This purpose can be understood and described by the fundamental particles that are atoms and molecules of matter. Is it possible to observe these particles or can they be compared? Can we count the number of atoms or molecules in a definite quantity of matter? Can a quantitative relationship be established by the number of atoms or molecules in definite quantity of matter?
We can get the answers of many such questions with the help of basic concepts of chemistry Chapter 1 of Class Science is a bridge to understand the nature. In other words, science is a continuous human effort to understand nature using systemic knowledge.
The study of chemistry is so wide and diversified, that it is classified in various disciplines like inorganic, organic, physical, analytical industrial, biochemistry etc. Chemistry is science of occurrence and synthetic composition, structure and properties of substance. The branches of science like chemistry, physics, biology, geology are interrelated to one another.
Chemistry plays an important role in our everyday life. Questions of this section will defiantly increase the mental level of the students as well as readers. MCQ questions are very good for the preparation for entrance exams and concept solving.
If you are having any suggestion for the improvement, your are welcome.

Klara was great to deal with and we got a lot of great information about the holiday.
I was very happy with the level of organisation and information that we were given for our trip. I loved that we got to keep a book that represented the sites visited on our trip. The big map with the route and sites to visit marked on it was also appreciated. We only needed to call the office once during our trip to change the itinerary and Larus was very accommodating. I would definitely use Nordic Visitor again. This was the trip of a lifetime.
It surpassed our expectations. We love Iceland - Mother Nature at her best. Every turn had a new adventure and we just didn't want it to end. Your company did a fabulous job in giving us travel options and lining everything up for our arrival.
I have used other travel agencies and I only wish they were as professional as you. Thank you for such a great time in your country. Annie was just superb to deal with both over the phone and with the internet.
She was extremely knowledgeable and very pleasant to work with. Loved Cocoa Mountain in Durness. We truly enjoyed Orkney Island and also the Islands of Harris and Lewis. Since we punctured a tire, we were grateful to have the insurance package. Petra was a pleasure to work with, and provided service above and beyond. The itinerary was customized to our needs with no reluctance or difficulty.
This is our second Nordic Visitor trip and they both have been wonderful trips. We've enjoyed many of the excursions you've recommended and are grateful for the expertise of your staff who planned our trips.
