Homologous series among the following is:
Show Hint
Remember: In a homologous series, the compounds have the same functional group and differ by a CH2 unit.
Updated On: Sep 6, 2025
- CH3OH and C2H5OH
- CH3COOH and CH3COCH3
- C2H5CHO and CH3OCH3
- C3H8 and C4H9OH
Hide Solution
Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: What is a Homologous Series?
A homologous series consists of organic compounds with the same functional group and similar chemical properties. The members of the series differ by a CH2 unit.
Step 2: Identifying the Homologous Series
- CH3OH (methanol) and C2H5OH (ethanol) are alcohols. They differ by a CH2 unit. Hence, they belong to the same homologous series (Alcohols).
- Other options do not show a consistent functional group or differ by a CH2 unit.
Step 3: Conclusion
The correct homologous series is CH3OH and C2H5OH.
\[
\boxed{\text{CH3OH and C2H5OH}}
\]
