Halogens 3.1.3

Question 1

What is the trend of Atomic Radius in the Halogens?

Answer 1

Increases down the group

Question 2

How does Boiling Point change in the Halogens?

Answer 2

Increase down the group
this is due to the molecules being diatomic and having more electroons, leading to greater induced dipole-dipole interaction.

Question 3

How does Reactivity change in the Halogens?

Answer 3

Decrease down the group as there is less attraction between the nucleus and outer shells
Therefore isn’t as capable of attracting electrons

Question 4

What is the trend of Halogens and Oxidising agents?

Answer 4

Halogens become weaker oxidising agents down the periodic table.
due to being less reactive

Chlorine: Pale green
Bromine: Orange
Iodine: Red/Brown

Question 6

What colour ar ethe Halogens when shaken with Cyclohexane?

Answer 6

Chlorine: White/yellow
Bromine: Orange/brown
Iodine: Purple/red (beatroot)
