The WebAssign questions for this textbook are from a set of questions developed by Dr. Kay Sandberg, an experienced organic chemistry instructor at North Carolina State University. These questions, covering the main topics in organic chemistry, have been correlated as closely as possible to the appropriate chapter in the textbook. Because these questions were not originally written for this textbook, it is recommended that you check each assigned problem to see if the material required for completing the question has been covered in your class.

Because it is customary in organic chemistry to publish a complete student solution guide for every end-of-chapter question, the student guide renders the textbook end-of-chapter questions unusable for an online homework system. Dr. Sandberg's set of questions provides an excellent solution to this problem.

A variety of response types are used in multipart questions such as fill-in-the blank, multiple choice, multiselect and numerical. Most importantly, there are many questions that require the students to draw a skeletal structure for an organic molecule using a web-based, online drawing tool in WebAssign. WebAssign grades these structures automatically, checking for stereo features, rings, chains, etc. by creating a unique SMILES string.

The question set has been extensively class-tested in multiple 200-student courses at NC State.

As often as possible, variables, numbers, or words have been randomized so that each student will receive a unique version.

You are free to duplicate a question and change it as you like for your class.
