The sec-butyl cation can react as both a Lewis acid and a Brønsted- Lowry acid in the presence of a water-sulfuric acid mixture. In each case, however, the product is different. The two reactions are: 2. H2o +H3O+ a. In which reaction does this cation react as a Lewis acid? In which does it react as a Brønsted-Lowry acid? b. Write Lewis structures for reactants and products and show by...
