Halogen Displacement Quiz

What is a displacement reaction with halogens?

• A displacement reaction with halogens does not involve the transfer of electrons.

• A less reactive halogen can displace a more reactive halogen from its compound.

• A displacement reaction with halogens involves the formation of a new compound.

• A more reactive halogen can displace a less reactive halogen from its compound.

Which halogen can displace bromine from a solution of potassium bromide?

• Chlorine

• Nitrogen

• Oxygen

• Sodium

In a displacement reaction with halogens, what happens to the more reactive halogen?

• It combines with the less reactive halogen

• It becomes less reactive

• It evaporates

• It displaces the less reactive halogen.

What is the chemical equation for the displacement of chlorine by bromine in a solution of potassium chloride?

• KCl + Br2 -> KBr + Cl

• 2KCl + Br2 -> 2KBr + Cl2

• KCl + Br -> KBr + Cl2

• 2KCl + 2Br2 -> 2KBr + 2Cl

What is the color change observed when chlorine displaces iodine from a solution of potassium iodide?

• Red

• Yellow

• Green

• Brown

What is the general trend in reactivity of halogens in displacement reactions?

• Reactivity increases as we move down the group

• Reactivity increases as we move up the group

• Reactivity is the same for all halogens

• Reactivity decreases as we move down the group

What is the product formed when fluorine displaces iodine from a solution of potassium iodide?

• Potassium chloride and iodine gas

• Potassium fluoride and chlorine gas

• Potassium fluoride and iodine gas

• Potassium bromide and iodine gas

What is the chemical equation for the displacement of iodine by chlorine in a solution of potassium iodide?

• KI + Cl2 -> KCl + I

• 2KI + Cl2 -> 2KCl + I2

• KCl + I2 -> KI + Cl2

• 2KCl + I2 -> 2KI + Cl2

What is the role of the halogen in a displacement reaction?

• It has no role in a displacement reaction

• It forms a compound with the metal

• It prevents the displacement reaction from occurring

• It is replaced by a more reactive halogen.
