In the following reaction identify the Lewis acid and Lewis base: In a reversible reaction, the reactant that has a SMILES string of CCO reacts with another reactant to yield a product. The second reactant has a SMILES string of CC(C)C with a positive charge at C 2. The product has a two-carbon chain. C 2 is bonded to two methyl groups and an oxygen atom, which carries a positive charge. The oxygen atom is further bonded to an ethyl group as well as a hydrogen atom.
