Lab Goals Two week lab Week 2 We want to ask a question about elimination reactions but we dont have one of the reagents 2chloro2methylbutane Week 1 Goal Make at least 30 mL of 2chloro2methylbutane. Benzene is aromatic: a cyclic conjugated compound with 6 . . electrons. Reactions of benzene lead to the retention of the aromatic core. Types of Reactions. Electrophilic. substitution. Diazonium. Most common reactions for aromatics involve replacement of ring . hydrogens. by other atoms or groups . (substitution reactions). Mechanism of Electrophilic Aromatic Substitution Reactions. Electrophile. Part 4: Reactions of Alcohols; Substitution . Rxns. Reactions of Alcohols. Combustion. General eq’n for an alcohol combusting completely in oxygen:. C. n. H. (2n+1). OH(l) + (2n+1)O. 2. (g) .  nCO. 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:. Coordination Chemistry IV. Reactions and Mechanisms. Coordination Compound Reactions. Goal is to understand reaction mechanisms. Primarily substitution reactions, most are rapid . Cu(H. 2. O). 6. 2+. 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.. Hydrocarbons . Essential idea. Structure, bonding and chemical reactions involving functional group inter-conversions are key strands in organic chemistry.. Learning outcomes . Understand:. Alkanes. have low reactivity and undergo free-radical substitution reactions.. Reactions and Distillation. S343. Lab Goals. We . want to . compare product distributions in elimination reactions. Does mechanism matter?. Experimental Flowchart. Conduct the . reactions with a partner. Generic Equation: Swap. R-X + Nu: .  R-Nu + :X. -. The problem lies in the mechanism.. Importance of Alkyl Halides. Precursor to many others. NUCLEOPHILIC SUBSTITUTION. Theory. . - nucleophile means ‘liking positive’. Newehy.
