Name the type of reaction: A + B -----> C

• A. Substitution
• B. Addition
• C. Elimination
• D. Polymerization

Answer: (B)

Two reactants joining to form a single product is an addition reaction. The idea is that atoms from A and B come together in one new molecule C, so you end up with one product made from both starting substances. This fits because there aren’t rearrangements of parts within a single molecule or the loss of a small molecule; instead, the two substances simply add together to build one compound. It differs from substitution, where part of a molecule is replaced by another group; from elimination, where a small molecule is removed to form a new structure; and from polymerization, where many units join to form a long chain.
