Mechanism 2: Electrophilic addition Flashcards
check folder for step by step example
what is an electrophile?
an electron pair acceptor
what are electrophiles attracted to?
areas of high electron density
what does the reaction mechanism of electrophilic reaction show?
it shows how electrophiles attack the double cc bond in alkenes
what forms when the cc double bond is broken?
a carbocation intermediate
what is a carbocation intermediate?
a C atom with only 3 bonds so has a positive charge
how stable are carbocations?
carbocations have varying stability
which carbocation is most stable?
tertiary carbocation is the most stable with primary carbocation the least
what is a primary carbonation?
the carbocation is bonded to one other carbon atom (secondary- 2 other C, tertiary- 3 other C)
which carbocation is more likely to form, in relation to stability?
the more stable the carbocation, the more likely it is to form
how many products are formed in electrophilic addition?
multiple, depending on the reaction
what is the major product of electrophilic addition?
the one that is formed via the most stable carbocation
alkene + halogen —>
dihaloalkane
alkene + hydrogen oxide—>
haloalkane
