Aromatic Compounds Ch 15 2 Electrophilic Aromatic Substitution Reactions Overall reaction Ch 15 3 Ch 15 4 A General Mechanism for Electro philic Aromatic Substitution Different chemistry with alkene. Type 1: A metal combines with a nonmetal to form a binary salt.. Example: A piece of lithium metal is dropped into a container of nitrogen gas.. 6Li (s) + N. 2. (g) . → 2Li. 3. N (. aq. ). Synthesis Reactions. In addition to substitution, alkyl halides can also undergo elimination reactions, which lead to the formation of alkenes.. As with substitution reactions, elimination reactions come in two mechanistic types:. ‘Encountering the play’. “It is so easy to lose the freshness of direct response to ‘first time’ encounter with a text, which will in time be overlaid by the experience of working, scene by scene, through the text. Most people who have seen this play throughout its life have probably only seen it once: . If a set of chemical reactions is taking place in a system, a . complete. mathematically independent sub-set is one where every reaction that is . not. included in the complete mathematically independent sub-set can be written as a linear combination of the reactions that . 1 – Nature of Chemical Reactions. 2 – Chemical Equations. 3 - Reaction Types. 4 – Reaction Rates and Equilibrium. State Standards. CLE.3203.1.9 – Apply the Laws of Conservation of Mass/Energy to balance chemical equations. . Ch. 8 – Chemical Reactions. Signs of a Chemical Reaction. Evolution of heat and light.

Prepared based on many others slides. Introduction. Goal is to understand reaction mechanisms. Three types of reactions: . Substitution. Redox. Ligand-Based. Primarily substitution reactions. :. M. ost substitution reactions are rapid . but some are slow. The . risk for development of a drug eruption is related to the following factors: age, gender, dose, and the nature of the medication itself. . Females . are . 1.3-1.5 . times more likely to develop drug eruptions, except in children under the age of 3 where boys are more likely to be affected. . Objective. To know about . electrophilic. substitution reactions. Success criteria. Understand . the mechanism of the . electrophilic. substitution reactions of . benzene. Understand this for . halogenation. All. chemical reactions either release or absorb energy. . The energy can take many forms: . HEAT. , . LIGHT. , . SOUND. , and . ELECTRICITY. . Chemical . bonds. are the source of this energy. .
