What examiners said
The other type of hydrocarbon was usually identified as an alkene. Common incorrect answers included named hydrocarbons such as methane, ethane and propane.
— Examiner report, October/November 2023, 0973/41 Q2(c)(i) (Cambridge)
Candidates generally followed the correct naming convention, recognising that the prefix for the first alkene was eth- and the last alkene was but-. The most common error was to try and include an additional hydrogen in the structure of propene.
— Examiner report, May/June 2023, 0973/42 Q2(b) (Cambridge)
Some candidates gained partial credit here. To gain full credit, responses needed to give greater detail.
