What examiners said
As one of only two elements which are liquid at room temperature and pressure, it was anticipated that more candidates would identify bromine from the list. For this paper, fewer than one third of the candidates chose bromine, with fluorine and ammonia being common incorrect answers. Candidates should be reminded that bottles which may be labelled as ‘ammonia’ in the school laboratory contain an a...
— Examiner report, May/June 2025, 0620/31 Q1(f) (Cambridge)
Candidates found this first question one of the most accessible questions on this paper and did reasonably well on it. They especially did very well on (d) and (i). Candidates struggled on (c).
— Examiner report, May/June 2025, 0620/32 Q1 (Cambridge)
Candidates struggled with this question and did not know that a diatomic molecule which is a solid at room temperature and pressure is iodine.
