Options
- AMethanoic acid
- BEthanoic acid
- CPropanoic acid
- DButanoic acidaa
Correct 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 -CH₂- group, which gives ethanoic acid ( CH₃COOH ). The second higher homologue is obtained by adding another -CH₂- group, which gives propanoic acid ( CH₃CH₂COOH ). Answer: Propanoic acid
