The author is trying to jump around on the concept he is trying to explain. Sometime, author used a long paragraph to explain a concept while at the end the point is still not clear.Examples in the text are not given in a consistent manner which causes lots of confusion to reader.
Some important concepts are not presented in the text, unsymmetrical substitution in the conjugated system for example.
I would recommend reader to read the book critically and do expect that things in the book are not 100% correct.

The second edition contained incredible errors regarding mechanistic organic chemistry, many of which were corrected by the third edition. No doubt, these errors were taught to a significant number of students, and have resulted in some ribbing of the authors by their peers. Nonetheless, the third edition still contains significant errors. Bright students will find those errors confusing, as they contradict what they learn about pKa's and acid/base chemistry within the text.

Text information states pKa values are for the conjugate acids of bases listed in tables, and this further confuses students, who assume the molecules listed are the acids themselves.

Incredible leaps of logic must be required for students to take sparse detail in the text and apply them to complex problems in the problem sets. Although the problems are enjoyable for Ph.D.'s in the field, they miss the mark regarding beginning students. I find the problems relevant and amusing, but they are often advanced or graduate level. In contrast,example problems in the text are quite simplistic.

It appears that the text attempts to address biochemistry, polymer and medicinal chemistry to some level - but must sacrifice content in the core areas of organic chemistry in order to satisfy the unwritten rule of a book of dimensions of 1.5" x 8" x 10" for the publisher.

The sidebars were a reasonable attempt to humanize chemistry. University academics are still scratching their heads as to why they continue to have trouble interesting students in chemistry - they need to look close to home regarding text and laboratory material. Both seem to provide an exercise in futility for U.S. students. Scientific method is taught in high school, and promptly forgotten. Logic and flow is missing today.

Good luck with the next edition!

Of all the Organic Chemistry text books I have reviewed, this one is at the top of the pile. It is logically organized and figures are well done. Brown & Foote do a great job of presenting the difficult subject matter.
