2. The sec-butyl cation can react as both a Lewis acid and a Bronsted. Lowry acid in the presence of a water-sulfuric acid mixture. In each however, the product is different. The two reactions are: case +HO In which reaction does this cation react as a Lewis acid? In which does it react as a Brønsted-Lowry acid? a. Write Lewis structures for reactants and products and show by the use of curved arrows how each reaction occurs. b. 3. Drawing good cyclohexane rings takes practice. Draw clear 3-dimensional drawings of the two chair conformations of methylcyclohexane. Determine which is the more stable conformer. Start by drawing a chair cyclohexane with no substituents and then add the substituents. Use wedges and dashes appropriately. Try to make your drawings a neat and clear as possible. 4. Draw structures for the following compounds a. 3-ethyl-4-methylcyclopentane b. 2,2,3,3-tetramethylbutane
