For two-semester/three-quarter courses in General, Organic, and Biological Chemistry, primarily for majors in Allied Health, and occasionally in Environmental Technology, Agriculture, and other majors. Also suitable for one-semester courses with a comprehensive approach. This best-selling text bears the hallmark of all John McMurry’s books.  On style, it is concise and avoids the ‘wordiness’ of most GOB texts.  On substance, it is unusual in its balance of chemical concepts to explain the quantitative aspects of chemistry, and provides greater depth of insight into the theoretical chemical principles.  This makes for a wider spectrum of the different angles from which to view chemistry, and thus, captures a greater number of students who can successfully learn from the book.  Demanding, yet logical, it also sets itself apart by requiring students to master concepts before they can move on to the next chapter.
