Homework Answers
1. Option D, rate= K[CH3Br][I-], since it is SN2 reaction and follow 2nd order kinetics.
2. Option B, Sn1 reaction since sterechemistry is retained.
3. No, mixture of Alkenes formed.
4. Yes, single product formed.

1. Sketch the reaction mechanism (including the final product) corresponding to the following description. Explain the answer thoroughly using concise sentences. o 1-bromo-1-methylcyclopentane is being reacted with sodium ethoxide in diethyl ether (set up the reaction – next you will get a description of the mechanism to draw). o Ethoxide will remove a proton from one of the carbons alpha to the carbon bonded to bromine. The electron pair from the carbon-hydrogen bond will move toward the 1 carbon to...

For the reduction of benzophenone to benzohydrol by NaBH4 1) Draw the reaction, showing the reactants and products. • What apparatus and conditions (solvent, temp., reaction time, etc) will be used for the reaction? (we are using ethanol and Buchner funnel filtration) • How will the benzhydrol product be isolated from the reaction mixture and how will it then be further purified? How will the product be characterized? • Identify which is the reducing agent and which is the oxidizing...

Alkyl halides may undergo elimination reactions with BrØnstead-Lowry bases in which the halide and an adjacent proton are lost to form a new π bond. Because of the loss of a proton and a halide anion the reactions are termed ‘dehydrohalogenation’. The two most common associated mechanisms are designated as either unimolecular (E1) or bimolecular (E2) elimination reactions based on reaction rate studies. E1 reactions proceed via a two-step mechanism that involves the cleavage of the leaving group (here the...
