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...
