- 18-48 4-Aminobenzoic acid is prepared from benzoic acid by the following two steps. Show reagents and experimental conditions to bring about each step.arrow_forward18-31 Formic acid is one of the components responsible for the sting of biting ants and is injected under the skin by bee and wasp stings. The pain can be relieved by rubbing the area of the sting with a paste of baking soda (NaHCO3) and water, which neutralizes the acid. Write an equation for this reaction.arrow_forward18-29 Complete the equations for these acid—base reactions. (a) (b) (c) (d) (e)arrow_forward
- 18-15 Draw a structural formula for the dimer formed when two molecules of formic acid interact by hydrogen bonding.arrow_forward8 (Chemical Connections 19C) Once it has been opened, and particularly if it has been left open to the air, a bottle of aspirin may develop a vinegar-like odor. Explain how this might happen.arrow_forward8 In Chapter 22, we will discuss a class of compounds called amino acids, so named because they contain both an amino group and a carboxyl group. Following is a structural formula for the amino acid alanine. What would you expect to be the major form of alanine present in aqueous solution (a) at pH 2.0, (b) at pH 5—6, and (c) at pH 11.0? Explain.arrow_forward
