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 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 \(CH_{2}\).
