• can members differ by CH2 or 8 electrons 12. Accident
• members have gradually changing physical properties (ex, boiling point, melting point, density) • waste sea management 11. Pollution prevention
prevention 1. Prevent waste
• as homologous series ascends, size of molecule increases (ex increases boiling point) A
