To determine the type of reaction represented by the general formula [tex]\(AB + CD \rightarrow AD + CB\)[/tex], let's analyze what is happening during this reaction.
1. Identify the Reactants and Products:
- Reactants: [tex]\(AB\)[/tex] and [tex]\(CD\)[/tex]
- Products: [tex]\(AD\)[/tex] and [tex]\(CB\)[/tex]
2. Composition Changes:
- In this reaction, the components [tex]\(A\)[/tex] and [tex]\(C\)[/tex] from the reactants switch partners to form new compounds. Specifically, [tex]\(A\)[/tex] from [tex]\(AB\)[/tex] pairs with [tex]\(D\)[/tex] from [tex]\(CD\)[/tex], and [tex]\(C\)[/tex] from [tex]\(CD\)[/tex] pairs with [tex]\(B\)[/tex] from [tex]\(AB\)[/tex].
- The result forms new compounds [tex]\(AD\)[/tex] and [tex]\(CB\)[/tex].
3. Type of Reaction:
- This type of chemical reaction involves an exchange of ions or elements between two compounds. Since the components of the reactants are interchanged to produce two new compounds, this signifies a double replacement (or double displacement) reaction.
4. Options Given:
- Synthesis: Two or more simple substances combine to form a more complex substance.
- Decomposition: A complex substance breaks down into two or more simpler substances.
- Oxidation: Typically involves the transfer of electrons and often includes the gain of oxygen or the loss of hydrogen.
- Replacement: Involves the exchange of components between reactants to form new compounds.
Considering the explanation above, we can conclude that the reaction with the general formula [tex]\(AB + CD \rightarrow AD + CB\)[/tex] is a replacement reaction.
Therefore, the correct answer is:
- Replacement.
- 4. in the list of options.
