Examiners report
Question 29 contained a mass spectrum and 44% of students chose the correct answer of C - ethanoic acid. There were comments that this was unfair without access to the data booklet. However, as the other molecules are clearly wrong this did not seem so difficult to do without the data booklet as they did have the periodic table.
