A student makes four statements about the physical properties of the halogens.
Statement 1: the colours of the halogens become darker down the group
Statement 2: bromine boils at a higher temperature than chlorine because the covalent bond between two bromine atoms is stronger
Statement 3: the melting points increase down the group because the forces between the molecules get stronger as the molecules get larger
Statement 4: fluorine has the lowest boiling point because it is the most reactive halogen
Which statements are correct?
1 and 3 only
2 and 3 only
1, 3 and 4 only
1, 2 and 3 only
106 exam-style questions on Edexcel GCSE Chemistry 7.2 Group 7, covering 7.2.1 Physical properties of the halogens, 7.2.2 Reactions of the halogens, 7.2.3 Relative reactivity and displacement reactions of the halogens, and 7.2.4 Halogen displacement as a redox reaction. Each one has a worked solution and a mark scheme showing where the marks go.
