Questions and Answers
What is a Single Displacement reaction?
A chemical reaction in which one element takes the place of another element in a compound, also known as a substitution reaction.
How can you tell that a Single Displacement reaction will occur?
It occurs between a compound and an element, with metals/halogens arranged by decreasing reactivity, and only if one metal is more reactive than the other.

Study Notes
Single Displacement Reactions Overview
- A Single Displacement reaction involves one element substituting another in a compound.
- Also referred to as a substitution reaction.
Identifying Single Displacement Reactions
- Reaction occurs between a compound and a free element.
- Reactants include metals or halogens arranged by reactivity.
- Reaction only takes place if the free element is more reactive than the element being replaced.
Types of Single Displacement Reactions
- Three distinct types of Single Displacement reactions exist.
First Type of Reaction
- Involves a metal displacing another metal in a compound.
- Example: Metal A replaces Metal B in a compound BC.
Second Type of Reaction
- Occurs between hydrogen and a metal with the acid as the reactant.
- Example: Metal displaces hydrogen in an acid compound (e.g., HCl).
Third Type of Reaction
- Involves a reaction between halogens.
- A more reactive halogen displaces a less reactive halogen in a compound.
General Formula
- Represented by the formula: A + BC → AC + B.
- Indicates that A displaces B from compound BC, forming a new compound AC and releasing B.
