What do curly arrow represent?
Curly arrows represent the movement of a pair of electrons
What are free radicals?
Free radicals are highly reactive species with an unpaired electron
What is a feature of free radicals?
A feature free radicals is they are usually extremely reactive
Drawin in the curly arrows and slight charges for this reaction mechanism
C = partial positive X = slight negative Curly arrow from lone pair of electrons towards carbon
What is heterolytic fission?
When covalent bond breaks in a way that allows the more electronegative atoms to take both the electrons from the bond to form a negative ion, leaving behind a positive ion
What is homolytic fission?
When covalent bond is broken in such a way that each atom takes an electron from the bond to form two radicals
What is a nucleophile?
An electron rich species that can donate a pair of electrons
What is an electrophile?
An electron deficient ion that attacks areas of high electron density
