Question

b. Write T (for true), F (for false), and N (for cannot be determined with the information given) after every statement posed about the carboxylic acid shown below. OH CI 1. The enantiomers have the same melting point. 2. The enantiomers have the same boiling point. 3. The enantiomers have the same solubility in water. 4. The enantiomers have the same magnitude of rotation of plane-polarised light The enantiomers have the same direction of rotation of plane-polarised light. The enantiomers have the same reaction rate with methanol. The enantiomers have the same pKa 5. 6. 7. 8. The enantiomers have the same rate of reaction with (S)-2-butanol

Explanation / Answer

True. Enantiomers differ only in their rotation of plane polarised light, and their reactions with other optically active compounds. All other properties are same. True. (see 1.) True. (see 1.) N. This has to be experimentally verified. False. Enantiomers rotate plane polarised light in opposite directions. True. methanol is an optically inactive compound hence enantiomers will react equally with it. True. (see 1.) False. (S)-2-butanol is an optically active compound, hence enantiomers will react differently.
