Chapter 16: Problem 11

The monopotassium salt of oxalic acid is present in certain leafy vegetables, including rhubarb. Both oxalic acid and its salts are poisonous in high concentrations. Draw the structural formula of monopotassium oxalate.

Short Answer

Expert verified
Answer: The structural formula of the monopotassium salt of oxalic acid is HOOC-COOK.

Step by step solution

01

Draw the structure of oxalic acid

Oxalic acid has the chemical formula C2H2O4. It consists of two carboxylic acid (COOH) groups connected by a carbon-carbon single bond. Draw the structure of oxalic acid as shown below: HOOC-COOH
02

Replace one hydrogen atom with a potassium atom

To form the monopotassium salt of oxalic acid, replace one of the hydrogen atoms (H) of the carboxylic acid groups with a potassium atom (K). The structure will now look like this: HOOC-COOK
03

Write the final structural formula

The structural formula for monopotassium oxalate is now complete. This represents the monopotassium salt of oxalic acid: HOOC-COOK

On a cyclohexane ring, an axial carboxyl group has a conformational energy of \(5.9 \mathrm{~kJ}\) (1.4 kcal)/mol relative to an equatorial carboxyl group. Consider the equilibrium for the alternative chair conformations of trans-1,4-cyclohexanedicarboxylic acid. Draw the less stable chair conformation on the left of the equilibrium arrows and the more stable chair on the right. Calculate \(\Delta \mathrm{G}^{0}\) for the equilibrium as written and calculate the ratio of the more stable chair to the less stable chair at \(25^{\circ} \mathrm{C}\).

So far, you have seen a number of reducing agents used in reactions. Functional groups react differently with each of these reagents. With this in mind, complete the following reaction, which is the last step in a synthesis of fexofenadine, a nonsedating antihistamine sold under the trade name Allegra.

We have studied Fischer esterification, in which a carboxylic acid is reacted with an alcohol in the presence of an acid catalyst to form an ester. Suppose that you start instead with a dicarboxylic acid such as terephthalic acid and a diol such as ethylene glycol. Show how Fischer esterification in this case can lead to a macromolecule with a molecular weight several thousand times that of the starting materials.

Arrange the compounds in each set in the order of increasing boiling point. (a) \(\mathrm{CH}_{3}\left(\mathrm{CH}_{2}\right)_{5} \mathrm{COOH}\) \(\mathrm{CH}_{3}\left(\mathrm{CH}_{2}\right)_{6} \mathrm{CHO}\) \(\mathrm{CH}_{3}\left(\mathrm{CH}_{2}\right)_{6} \mathrm{CH}_{2} \mathrm{OH}\)
