IB Chemistry SL 3.2.3 Homologous Series

Practise recognising an organic homologous series from its functional group and general formula. State that successive members differ by CH₂, compare molecular and empirical…

Exam points

match a displayed structure or formula to its organic homologous series
state or apply a general formula such as CnH2n for acyclic monoalkenes
identify successive members by the same functional group and a CH₂ increment

[Maximum number: 1]

Alkenes, such as A (shown below), are important intermediates in the petrochemical industry because they undergo addition reactions to produce a wide variety of products, such as the conversion shown below.
