Correct option is C
Correct Answer: (C) CH₃ COCH₃ and C₂H₅ COCH₃
Explanation:
Homologous series are groups of organic compounds that share the same functional group and follow a similar structural pattern, differing only by a repeating unit, typically a CH₂ group.
Homologous series are groups of organic compounds that share the same functional group and follow a similar structural pattern, differing only by a repeating unit, typically a CH₂ group.
- CH₃COCH₃ (acetone) and C₂H₅COCH₃ (ethyl ketone): Both are ketones and belong to the same homologous series of ketones. They differ by a CH₂ group.
Other Options:
- CH₃OH (methanol) and HCOOH (formic acid): Methanol is an alcohol, while formic acid is a carboxylic acid. These belong to different homologous series.
- C₂H₅OH (ethanol) and CH₃COOH (acetic acid): Ethanol is an alcohol, while acetic acid is a carboxylic acid, so they belong to different homologous series.
- CH₃CHO (acetaldehyde) and CH₃OH (methanol): Acetaldehyde is an aldehyde, while methanol is an alcohol, so they belong to different homologous series.
