Which of the following factors characterize members of the same homologous series?

A. The chemical property change gradually throughout the series
B. physical properties of members are similar
C. They have the same molecular formula
D. Successive members undergo changes in molecular formula by CH2

Correct Answer: Option D

D. Successive members undergo changes in molecular formula by CH2
