Reactivity of Halogens with Iron

What happens to the reactivity of halogens as you go down the group in the periodic table?

• It increases.

• It decreases.

• It remains the same.

• It fluctuates.

Which halogen reacts most vigorously with iron wool?

• Iodine

• Bromine

• Chlorine

• Astatine

What is the product formed when iron reacts with chlorine?

• Iron (II) chloride

• Iron (III) chloride

• Iron (III) bromide

• Iron (II) iodide

What is the balanced chemical equation for the reaction between iron and bromine?

How does iodine differ from chlorine and bromine in its reaction with iron?

• Iodine forms iron (III) iodide.

• Iodine forms iron (II) iodide.

• Iodine forms iron (IV) iodide.

• Iodine does not react with iron.

Why does iodine form iron (II) iodide instead of iron (III) iodide?

• Iodine is better at attracting electrons than chlorine and bromine.

• Iodine can only remove 2 electrons from iron.

• Iodine can remove 3 electrons from iron.

• Iodine does not react with iron.

Which of the following statements is true about comparing the the displacement reactions of halogens with the reaction with iron?

• Displacement provides weaker evidence of reactivity trends.

• Displacement provides stronger evidence of reactivity trends.

• Displacement does not involve competition between halogens.

• Displacement is not related to reactivity trends.

What is the general trend in the ability of halogens to attract electrons as you go down the group?

• It increases.

• It decreases.

• It remains constant.

• It fluctuates.
