What are reaction intermediates ? How are they generated by bond fission?
Answers
i) Reaction intermediates are the chemical species which are produced from the reactants during the reaction and products are formed on further reactions.
ii) The bond fission is of two types i) Homolytic bond fission and ii) Heterolytic bond fission.
iii) Free radicals are produced as intermediates during hemolytic bond fission.
iv) “Carbocation and Carbanion” are produced as intermediates during heterolytic fission.
Answer:
In chemistry, a reactive intermediate or an intermediate is a short-lived, high-energy, highly reactive molecule. When generated in a chemical reaction, it will quickly convert into a more stable molecule.
There are three intermediate species carbocation, carbanion and free radical.
Carbocation and carbanion are generated by hetrolytic fission.
Free radical is generated by homolytical fission.
Explanation:
Whereas homolytic fission means as the cleavage in which a covalent bond breaks in such a way that each atom takes away one electron of the shared pair. They contain an unpaired electron. The bond is broken evenly in the homolytic fission.
heterolytic fission is a type of bond fission in which a covalent bond between two chemical species is broken in an unequal manner, resulting in the bond pair of electrons being retained by one of the chemical species
