प्रश्न
How can ethanol and ethanoic acid be differentiated on the basis of their physical properties?
उत्तर
Differentiation based on physical characteristics:
- Ethanol emits a specific, generally agreeable odour reminiscent of alcohol. In contrast, ethanoic acid exudes a vinegar-like aroma.
- Ethanol vaporizes at a lower temperature, 351 K, while ethanoic acid has a higher boiling point of 391 K.
- Ethanol exhibits a neutral behavior and does not alter the color of litmus paper, be it blue or red. On the other hand, ethanoic acid exhibits acidic properties, turning blue litmus paper red upon contact.
