Fission oF covalent BonD!! ExPlain
Answers
Explanation:
In heterolytic fission, a covalent bond breaks in such a way that one of the bonded atoms gets both of the shared electrons. ... In homolytic fission, a covalent bond breaks in such a way that each of the bonded atoms gets one of the shared electrons.
Answer:
We know that a covalent bond is a bond formed between two atoms by sharing of electrons. Now let us consider a covalent bond formed between two atoms A and B. Each atom donates one electron to the bond, so two electrons are being shared between A and B.
A + B → A-B
Now if we break this bond, following are the two possibilities
(1) Homolytic bond fission
The first possibility is that the bond is cleaved in such a way that each atom gets one electron each. We can say that the bond is cleaved evenly. Thus
A-B → A. + B.
(2) Heterolytic bond cleavage
The second possibility is that the bond is not cleaved evenly. In this case, both the electrons forming the bond go to one atom, while the other atom does not get any electron. This results in the formation of charged species. We can represent this as follows
A-B → A- + B+
