For that reason, drill in nomenclature, formula writing, and reaction prediction and equation writing is usually a major part of any introductory course in organic and biochemistry. Few teachers are confronted with the problem of too many practice exercises. Indeed, we are likely to hear requests for more and more practice problems from teachers and students alike.

The purpose of this copy master set is to augment the problems in nomenclature, formula writing, and reaction prediction, and equation writing normally found in most organic and biochemistry texts. The problems were originally prepared to supplement the text, The Chemistry of Carbon Compounds, by David E. Newton. They cover, however, a wide range of difficulty. Each practice exercise includes some very basic problems, some exercises of moderate difficulty, and some activities at an advanced level.

Our expectation is that the problem sheets will be of value to an introductory high school chemistry class in which some attention is given to the subject of organic chemistry. They will be especially suitable for high school classes that devote extended periods of time to the subject. And, they should prove to be useful in introductory courses in organic and biochemistry at the college level. The author has tested all exercises with his own classes in Chemistry of Life Processes, an introductory course in organic and biochemistry for non-majors.

The exercise sheets in this set can be assigned as part of the regular class work for all students. Or they can be used as supplementary work for students who need extra practice on a topic. Finally, they may be used as "challenge" work for students who are eager to go beyond the standard curriculum available in your course.
