Which term best describes this reaction?

condensation polymerization
addition polymerization
hydrohalogenation
hydration

The best term that describes the reaction is addition polymerization

Explanation:

Polymerization is a process which small molecules, monomers, undergo a chemical reaction to form polymer chains. The two general types are: addition polymerization and condensation polymerization.

Addition polymerization occurs when monomers reacts by the opening of the double bond to form a long carbon chain. The reaction continues until the reactive intermediate is destroyed in a termination reaction. This is a major process of producing polymers such as: poly(ethene) and poly(propene). It process has three stages which are: initiation, propagation, and termination.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
