This brilliantly innovative textbook constructs organic chemistry from the ground up. By focusing on the points of reactivities in organic molecules -- showing why they are reactive, what kinds of moieties react by certain pathways, and how surroundings may alter the reactivity -- this text allows students to approach more and more complex molecules with enhanced understanding. Also noteworthy are the biochemical examples for their variety, substance, and depth. Despite its unique emphasis on reactivity, the book facilitates easy adoption by covering organic compound classes in a traditional order. Hundreds of worked examples and student exercises combine with clear writing and sound pedagogy to make this text an exceptional choice. Key Features of This Edition: Organizes organic reactions by mechanism rather than by functional group. Provides complete and integrated treatment of biochemical processes with organic reaction mechanisms.
