Which term identifies a type of organic reaction? (1) deposition
(2) distillation
(3) polymerization
(4) vaporization
Solution: Deposition and vaporization represent phase changes. Distillation is an organic chemistry laboratory procedure to separate liquids based on their boiling point. Polymerization is an organic reaction where monomers (identical subunits) are bonded together to form a polymer (like subway cars forming a train). 3 is the correct answer.
