Which of the following factors characterize members of the same homologous series?
- The chemical property change gradually throughout the series
- physical properties of members are similar
- They have the same molecular formular
-
Successive members undergo changes in molecular formula by \(CH_{2}\)
The correct answer is: D
Explanation
The difference between every successive member of the same homologous series is always \(CH_{2}\) eg methane is \(CH_{4}\) and ethane is \(C_{2}H_{6}\), difference being \(CH_{2}\).
