Single Displacement Reactions Overview

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.
