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.

How many types of different Single Displacement Reactions are there?

Describe the first type of Single Displacement reaction.

It occurs between a metal and another metal, where one metal replaces the other metal in a compound. Signup and view all the answers

Describe the second type of Single Displacement reaction.

It occurs between hydrogen and a metal, involving an acid as the reactant; the metal replaces the element in the acid compound. Signup and view all the answers

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.
