CHEM - Halogen Reactivity & Displacement Reaction
Chemistry, Displacement Reactions, Halogen IBDP | DSE | GCE | IAL | AP Chemistry
Consider the example below👁🗨
The reactivity of Group 7 elements decreases as we move down the group.
When moving down the group, the atoms get larger thus the outermost shell gets further from the nucleus.
As a result, the attraction between the nucleus and electrons gets weaker, so an electron is less easily gained.
2.14 and 2.15🤔
Displacement Reaction of Chlorine and Potassium Bromide
2KBr(aq) + Cl2(g) → 2KCL(aq) + Br2(aq)
Displacement Reaction of Chlorine and Potassium Iodide
2KI(aq) + Cl2(g) → 2KCL(aq) + I2(aq)
Displacement Reaction of bromine and sodium bromide
Lastly, here is a sample question🧐
The answer is B as only the reactions of I and III is possible
