PDF-Organic Mechanisms: Radicals

1 Ch 1 Introduction to Radicals The idea of a substituted carbon atom with 7 valence electrons being a reactive intermediate was established and accepted in around the 1930x2019s The two most f. 1 Chapter 4 Photochemistry “The Chemistry of Excited States” 2 Photochemistry is the study of what happens when molecules absorb quanta of light (energy).

Sue Blakely. ALkanes. Chapter 10.2:. Structure, bonding and chemical reactions involving functional group inter-conversions are key strands in organic chemistry. Chapter 20.1:. Key organic reaction types include nucleophilic substitution, electrophilic addition, electrophilic substitution, and redox reactions. Reaction mechanisms vary and help in understanding the different types of reactions taking place.. Lecture 15. Thanks to Colette . Heald. for many of the slides in this lecture.
