Chain reaction chemistry definition
WebThe reaction is a lengthy process and the molecular mass is increased at a very slow rate. An example of step-growth polymerization is condensation polymerization where a water molecule is evolved in the reaction when the chain is lengthened. Condensation Polymerization WebAug 17, 2024 · What is PCR? Sometimes called "molecular photocopying," the polymerase chain reaction (PCR) is a fast and inexpensive technique used to "amplify" - copy - small segments of DNA. Because significant amounts of a sample of DNA are necessary for molecular and genetic analyses, studies of isolated pieces of DNA are nearly impossible …

WebIUPAC defines chain propagation as a reaction of an active center on the growing polymer molecule, which adds one monomer molecule to form a new polymer molecule (RM 1 °) one repeat unit longer. For radical polymerization, the active center remains an atom with an unpaired electron. WebThe reaction proceeds through the radical chain mechanism. The radical chain mechanism is characterized by three steps: initiation, propagation and termination. Initiation requires an input of energy but after that the reaction is self-sustaining.
