Predict the predominant alkene product that would form when 2-bromo-2-methylpentane is treated with sodium methoxide in methanol. If the base were changed to KOC(CH2CH3)3 would the same alkene predominate? If not, why? What would be the structure of this alternate product be, if it formed?

3. If sodium methoxide in methanol was used in place of potassium t butanol, your GC analysis would look much more like the 2-butanol/sulfuric acid reaction products. In addition, a new, non-alkene product would be present in the GC analysis from a competing, non-elimination mechanism. Explain why the alkene distribution would change, what the new product would be, and why this new product would form. 4.
