write a note on heterolytic fission.give two examples of nucleophiles
Answers
Answer:
Most chemical reactions involve the breakage of existing chemical bonds and the formation of new ones. However, chemical bonds can be broken in multiple ways. Furthermore, the manner in which a chemical bond breaks plays a vital role in deciding the overall outcome of the chemical reaction. The breakage of a chemical bond (usually a covalent bond) is often referred to as bond fission. The two primary types of bond fission are homolytic fission and heterolytic fission
Explanation:
Homolytic fission (sometimes referred to as hemolysis) is a type of bond fission that involves the dissociation of a given molecule wherein one electron is retained by each of the original fragments of the molecule. Therefore, when a neutrally charged molecule is subjected to homolytic fission, two free radicals are obtained as the product (since each of the chemical species retains one electron from the bond pair).
It can be noted that homolytic fission is also known as homolytic cleavage or bond homolysis. These terms are derived from the Greek root ‘homo’, and the term can be roughly translated as ‘equal breaking’.

Question:-
write a note on heterolytic
Answer:
Heterolytic fission, also known as heterolysis, 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 (while the other species does not retain any of the electrons from the ...
Question:-
.give two examples of nucleophiles
Answer:-
Examples of nucleophiles are anions such as Cl−, or a compound with a lone pair of electrons such as NH3 (ammonia), PR3. In the example below, the oxygen of the hydroxide ion donates an electron pair to form a new chemical bond with the carbon at the end of the bromopropane molecule.
