Question

Which of the following statements about ethanoic acid and methyl methanoate are correct ?

(1) They are functional group isomers with the molecular formula C₂H₄O₂.

(2) They belong to different homologous series.

(3) They have different chemical properties.

CH₃COOH and HCOOCH₃ are both C₂H₄O₂ but one is a carboxylic acid and the other an ester.

Different functional groups mean different series and different properties, so all three statements are correct.
