Solution

Correct Answer:

-CH₂- unit

A Homologous Series is a group of organic compounds having the same functional group and similar chemical properties.

  • Successive members differ by a Methylene group () unit.
  • This difference leads to a difference in molecular mass of ().
  • Regular progression in physical properties (like boiling point) is observed as the chain length increases within the series.

This easy difficulty chemistry question is from the chapter some basic principles of organic chemistry, covering the topic of homologous series. It appeared in the 2025 exam.
