The propagation phase describes the ‘chain’ part of chain reactions. Once a reactive free radical is generated, it can react with stable molecules to form new free radicals. … Propagation steps often involve hydrogen abstraction or addition of the radical to double bonds.
In this regard, what is chain terminating step?
Chain termination is any chemical reaction that ceases the formation of reactive intermediates in a chain propagation step in the course of a polymerization, effectively bringing it to a halt. IUPAC definition. Chemical reaction in which a chain carrier is converted irreversibly into.
Simply so, what do you mean by propagation?
: the act or action of propagating: such as. a : increase (as of a kind of organism) in numbers. b : the spreading of something (such as a belief) abroad or into new regions. c : enlargement or extension (as of a crack) in a solid body.
What is plant propagation?
Plant propagation is the process of creating new plants. … The resulting new plant is genetically identical its parent. Asexual propagation involves the vegetative parts of a plant: stems, roots, or leaves.
What happens propagation?
A Step Where There Is No Net Gain Or Loss Of Free Radicals Is Called “Propagation” … So there is no net increase in the number of free radicals. This type of step is referred to as “propagation”.
Why was chain fired at a certain point?
When the reactions are incubated at a temperature suitable for the DNA polymerase, nucleotides that are complementary to the bases on the template are added onto the end of the attached primer. … If, by chance, the DNA polymerase adds a dideoxynucleotide, chain growth is terminated at that point.
What is a free Radica?
A free radical can be defined as any molecular species capable of independent existence that contains an unpaired electron in an atomic orbital. … Many radicals are unstable and highly reactive. They can either donate an electron to or accept an electron from other molecules, therefore behaving as oxidants or reductants.
