Take Free Practice Test On 2026 JAMB UTME, Post UTME, WAEC SSCE, GCE, NECO SSCE
  • A The chemical property change gradually throughout the series
  • B Physical properties of members are similar
  • C They have the same molecular formular
  • D Successive members undergo changes in molecular formula by \(CH_{2}\)
Correct Answer: Option 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 \(CH_{2}\).
