What is a free radical substitution?

In organic chemistry, a radical-substitution reaction is a substitution reaction involving free radicals as a reactive intermediate. The reaction always involves at least two steps, and possibly a third. In the first step called initiation (2,3) a free radical is created by homolysis.
A.

What is a chlorine radical?

In chemistry, a radical (more precisely, a free radical) is an atom, molecule, or ion that has an unpaired valence electron.
  • Why are free radicals bad?

    Once formed these highly reactive radicals can start a chain reaction, like dominoes. Their chief danger comes from the damage they can do when they react with important cellular components such as DNA, or the cell membrane. Cells may function poorly or die if this occurs.
  • What is a free radical reaction?

    A free-radical reaction is any chemical reaction involving free radicals. When radical reactions are part of organic synthesis the radicals are often generated from radical initiators such as peroxides or azobis compounds.
  • What is a radical person?

    radical. In more everyday language, a radical is someone who has very extreme views, so you could say that their views are different from the root up. Similarly, a radical flaw or change is a fundamental one whereas a radical design or idea is very new and innovative.
B.

Are chlorine radicals unreactive?

It has been proposed that the chlorine atom could be a significant reactive free radical in the troposphere (6), as it is in the stratosphere, where it is responsible for ozone depletion (7). Further, reactive chlorine atoms quickly end up as HCl, which is removed via rainout.

  • Who are the radicals?

    In Congress, the most influential Radical Republicans were U.S. Senator Charles Sumner and U.S. Representative Thaddeus Stevens. They led the call for a war that would end slavery.
C.

Can benzene undergo free radical substitution?

however, in benzene rings, because the C atoms all posses an overlapping p orbital that contains delocalised e, it is very stable. higher energy is needed to overcome the C-H bond in benzene rings. also, benzene undergoes electrophilic substitution, not free radical substitution.
  • What is meant by HV in chemistry?

    when referring to the quantization of energy, we use the equation. (delta)E = hf. meaning plancks constant times frequency. in organic chemistry, I also see "hv" over the reaction arrow for rxns that use high energy light, like UV.

  • How do you measure hardness?

    Mohs Hardness Test. As common sense dictates, Mohs Scale is based on the fact that a harder material will scratch a softer one. By using a simple scratch test, you can determine the relative hardness of an unknown mineral. Select a fresh, clean surface on the specimen to be tested.
