A chemical reaction where the general formula is [tex]\( AB + CD \rightarrow AD + CB \)[/tex] is referred to as a replacement reaction.
Here's the step-by-step reasoning:
1. Identify the reactants and products: The reaction starts with two reactants, [tex]\(AB\)[/tex] and [tex]\(CD\)[/tex], and produces two new products, [tex]\(AD\)[/tex] and [tex]\(CB\)[/tex].
2. Analyze the reactants: In the given formula, [tex]\(AB\)[/tex] and [tex]\(CD\)[/tex] are compounds composed of the elements [tex]\(A\)[/tex], [tex]\(B\)[/tex], [tex]\(C\)[/tex], and [tex]\(D\)[/tex].
3. Examine the transformation: During the reaction, the constituents of the reactant compounds rearrange to form the products [tex]\(AD\)[/tex] and [tex]\(CB\)[/tex]. Specifically, the [tex]\(A\)[/tex] from [tex]\(AB\)[/tex] combines with the [tex]\(D\)[/tex] from [tex]\(CD\)[/tex] to form [tex]\(AD\)[/tex], and the [tex]\(C\)[/tex] from [tex]\(CD\)[/tex] combines with the [tex]\(B\)[/tex] from [tex]\(AB\)[/tex] to form [tex]\(CB\)[/tex].
4. Classify the reaction type: The hallmark of a replacement reaction is that ions or elements from two different compounds exchange places. In other words, parts of the two reactant compounds switch partners to create two new compounds.
Therefore, this type of reaction where parts of two compounds switch places is known as a replacement reaction.
