Which one of the following compounds belongs to the homologous series of aldehydes?
Correct answer: C. Option C
- A. Option A
- B. Option B
- C. Option C
- D. Option D
Explanation
Homologous series is a family of hydrocarbons with similar chemical properties who share the same general formula. So for aldehydes RCHO is the general formula and HCHO would be the first member of homologous series of aldehydes, CH3CHO and CH3CH2CHO would be the 2nd and 3rd respectively.

About Aldehydes and Ketones
Aldehydes and ketones contain the polar carbonyl group, but aldehydes are generally more readily oxidised and more reactive than ketones. Coverage includes preparation by oxidation or reduction routes, nucleophilic addition of reagents such as hydrogen cyanide and bisulfite, and tests that distinguish aldehydes from ketones.
