Solution

Para determinar cuáles de los nombres IUPAC representan ácidos carboxílicos, debemos identificar los compuestos que contienen el grupo funcional -COOH (carboxilo). Vamos a analizar cada uno de los nombres proporcionados:

  1. Benzenecarboxylic acid: Este nombre indica un ácido carboxílico con un grupo carboxilo unido a un anillo bencénico. Es un ácido carboxílico.
  2. 3,3,3-trifluoropropanoic acid: Este nombre indica un ácido carboxílico con tres átomos de flúor en el tercer carbono de una cadena de tres carbonos. Es un ácido carboxílico.
  3. N,N-dimethylbutanamide: Este nombre indica una amida, no un ácido carboxílico.
  4. 2-ethylbutanoic acid: Este nombre indica un ácido carboxílico con un grupo etilo en el segundo carbono de una cadena de cuatro carbonos. Es un ácido carboxílico.
  5. Ethyl benzoate: Este nombre indica un éster, no un ácido carboxílico.

Por lo tanto, los nombres IUPAC que representan ácidos carboxílicos son:

  • Benzenecarboxylic acid
  • 3,3,3-trifluoropropanoic acid
  • 2-ethylbutanoic acid
