- C. Propanoic acid
- D. Butanoic acidaa
Answer
C. Propanoic acid
Step-by-step solution
Formic acid is the first member of the carboxylic acid homologous series with the IUPAC name methanoic acid (HCOOH). The first higher homologue is obtained by adding one -CH_2- group, which gives ethanoic acid (CH_3COOH). The second higher homologue is obtained by adding another -CH_2- group, which gives propanoic acid (CH_3CH_2COOH). Answer: Propanoic acid
