What is Zaitsev’s rule? Give the mechanism for the acid-catalyzed E1 reaction of 2-butanol. Give the mechanism for the base-catalyzed E2 reaction of 2-bromobutane. Draw all possible products. You expect three products from the elimination reaction 2-butanol. What are they? The E2 mechanism is a one-step mechanism. True or False? Explain. Which of these two alcohols would you expect to be more reactive under H3PO4/aqueous conditions? Why? Give the structure of the main product in both cases. 1-phenyl-1-propanol 1 -cyclohexyl-1-propanol...

complete #1 and #2 and please explain!
Nucleophilic Substitutions: Competing Nucleophiles Dry Lab Name When an alcohol (substrate) is placed in an excess equimolar amounts of chloride ions and bromide ions in acid media the corresponding alkyl halides are obtained. The ratio of the alkyl halides depends on several factors: the nature of the substrate, the reaction conditions, the solvent and the mechanism of the reaction.

Need help with number 2 and 3 on the postlab section.
Elimination Reactions Background The purpose of this lab is to prepare an alkene by dehydration of an alcohol in the presence of an acid catalyst Elimination reactions often result in the formation of multiple products. In this lab, 2-methylcyclohexanol is dehydrated to form an alkene. The product will be analyzed by GC-MS to determine the ratio of alkene isomers formed. You will need to determine the mechanism of the...

Pre-lab Questions:
Importance A one-step preparation of aspirin from its precursor, salicylic acid, via an ester formation illustrates one of synthetic organic chemistry's most important uses, making the drugs that treat all types of illnesses. OH HOOH Background Aspirin is a prodrug of salicylic acid, the actual active drug. A compound related to salicylic acid, salicin, was first isolated from willow bark in the mid 1700's, but willow-bark extract was used by the ancient Greeks as a treatment for pain...

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....
