A Review Enols and Enolates Synthetic Detergents Why do many students have difficulty preparing themselves for organic chemistry exams? Certainly, there are several contributing factors, including inefficient study habits, but perhaps the most dominant factor is a fundamental disconnect between what students learn in the lecture hall and the tasks expected of them during an exam.

To illustrate the disconnect, consider the following analogy. Students invest significant time studying the information that was presented, and on the last day of the course, the final exam consists of riding a bike for a distance of feet.

Organic Chemistry, 2nd Edition

A few students may have innate talents and can accomplish the task without falling. But most students will fall several times, slowly making it to the finish line, bruised and hurt; and many students will not be able to ride for even one second without falling.

Because there is a disconnect between what the students learned and what they were expected to do for their exam. Many years ago, I noticed that a similar disconnect exists in traditional organic chemistry instruction.

That is, learning organic chemistry is much like bicycle riding; just as the students in the bike-riding analogy were expected to ride a bike after attending lectures, it is often expected that organic chemistry students will independently develop the necessary skills for solving problems.

While a few students have innate talents and are able to develop the necessary skills independently, most students require guidance.

This guidance was not consistently integrated within existing textbooks, prompting me to write the first edition of my textbook, Organic Chemistry, 1e. The main goal of my text was to employ a skills-based approach to bridge the gap between theory concepts and practice problem-solving skills.

The phenomenal success of the first edition has been extremely gratifying because it provides strong evidence that my skills-based approach is indeed effective at bridging the gap described above.

I firmly believe that the scientific discipline of organic chemistry is NOT merely a compilation of principles, but rather, it is a disciplined method of thought and analysis. Students must certainly understand the concepts and principles, but more importantly, students must learn to think like organic chemists.

That is the true essence of organic chemistry. The textbook includes all of the concepts typically covered in an organic chemistry textbook, complete with conceptual checkpoints that promote mastery of the concepts, but special emphasis is placed on skills development through SkillBuilders to support these concepts.

Each SkillBuilder contains 3 parts: These problems include conceptual, cumulative, and applied problems that encourage students to think outside of the box. Sometimes problems that foreshadow concepts introduced in later chapters are also included.

This emphasis upon skills development will provide students with a greater opportunity to develop proficiency in the key skills necessary to succeed in organic chemistry.

Certainly, not all necessary skills can be covered in a textbook. However, there are certain skills that are fundamental to all other skills. As an example, resonance structures are used repeatedly throughout the course, and students must become masters of resonance structures early in the course.

Therefore a significant portion of Chapter 2 is devoted to pattern-recognition for drawing resonance structures. Rather than just providing a list of rules and then a few follow-up problems, the skills-based approach provides students with a series of skills, each of which must be mastered in sequence.

Each skill is reinforced with numerous practice problems. The sequence of skills is designed to foster and develop proficiency in drawing resonance structures. As another example of the skills-based approach, Chapter 7, Substitution Reactions, places special emphasis on the skills necessary for drawing all of the mechanistic steps for SN2 and SN1 processes.

Students are often confused when they see an SN1 process whose mechanism is comprised of four or five mechanistic steps proton transfers, carbocation rearrangements, etc. This chapter contains a novel approach that trains students to identify the number of mechanistic steps required in a substitution process.

Students are provided with numerous examples and are given ample opportunity to practice drawing mechanisms. The skills-based approach to organic chemistry instruction is a unique approach.

Certainly, other textbooks contain tips for problem solving, but no other textbook consistently presents skills development as the primary vehicle for instruction. Specifically, the first edition manuscript was reviewed by nearly professors and over 5, students. In preparing the second edition, peer review has played an equally prominent role.

We have received a tremendous amount of input from the market, including surveys, class tests, diary reviews, and phone interviews. All of this input has been carefully culled and has been instrumental in identifying the focus of the second edition.

Literature-based Challenge Problems The first edition of my textbook, Organic Chemistry 1e, was written to address a gap between theory concepts and practice problem-solving skills.

In Organic Chemistry 2e, I have endeavored to bridge yet another gap between theory and practice. Specifically, students who have studied organic chemistry for an entire year are often left profoundly disconnected from the dynamic and exciting world of research in the field of organic chemistry.MOLECULAR ORBITAL DIAGRAM KEY Draw molecular orbital diagrams for each of the following molecules or ions.
