4.
What is mechanism of the reaction ?
5.
What are organic reactions?
1.
The types of reagents that promote homolytic cleavage in substrate are called as free radical initiators. They are short lived and are highly reactive.
2.
(i) Homolytic cleavage is the process in which a covalent bond breaks symmetrically in such way that each of the bonded atoms retains one electron.
(ii) This type of cleavage occurs under high temperature or in the presence of UV light.
(iii) In a compound containing non-polar covalent bond formed between atoms of similar electronegativity, in such molecules the cleavage of bonds results into free radicals.
(iv) For example, ethane undergo homolytic fission to produce, two methyl free radicals.
3.
There are three types of fission of a covalent bond.
They are,
(i) Homolytic cleavage
(ii) Heterolytic cleavage
4.
In the organic reactions, that series of simple steps which collectively represent the chemical change, from substrate to product, this is called as the mechanism of the reaction. The sloweststep in the mechanism determines the overall rate of the reaction.
5.
Substrate is an organic molecule reacts with reagent, which may be an organic, inorganic or any agent like heat, photon etc, that brings about the chemical change to form a product, this is known as organic reactions.
