MCQ
What is not true about homologous series?
  • A
    All members have similar chemical properties.
  • B
    They have identical physical properties.
  • C
    They can be represented by a general formula.
  • D
    None of the above.
✓

Answer

  1. They have identical physical properties.

Explanation:

Homologous series differ by a CH2​ group. They have similar chemical properties as they have a common functional group.

They can be represented by a general formula for alkanes, alkenes, alkynes, and other functional groups.

However, as the molecular mass increases in a homologous series, a gradation in physical properties is observed. So, they do not have identical physical properties.
