Question

this reaction eventually forms this product.
which type of reaction is represented by these diagrams?
elimination
substitution
addition polymerization
condensation polymerization

Explanation:

1. In elimination reactions, a small molecule is removed from a reactant. Here, that's not the case.
2. In substitution reactions, one atom or group is replaced by another. This is not what's happening.
3. In addition polymerization, monomers with double - bonds add together without losing any small molecules. But here, a small molecule (like water) is likely lost.
4. In condensation polymerization, monomers react with the loss of a small molecule (such as water) to form a polymer. The given reactant has functional groups that can react to form ester linkages and release water, forming a polymer as shown in the product. This is characteristic of condensation polymerization.

Answer:

condensation polymerization
