Reaction Mechanisms Flashcards
1
Q
define a nucleophile
A
Something that is attracted to the nucleus.
- usually has negative charge
2
Q
define electrophile
A
is attracted to electrons
- usually positive
3
Q
name the 2 types of bond fission (split)
A
- heterolytic bond fission
- homolytic bond fission
4
Q
what kind of fission has a double-headed arrow
A
heterolytic bond fission
5
Q
what kind of fission has a single-headed arrow
A
homolytic bond fission
6
Q
what is nucleophilic substitution
A
involves a nucleophile (-) attacks a nucleus (+) of a C atom. To swap/substitute with a nucleophilic group already on the carbon chain
7
Q
what is electrophilic addition
A
involves the addition of an electrophile (such as H, Br) to a molecule which contains an electron rich region (c=c)
8
Q
What is carbocation stability
A
- carbocations are unstable intermediates
- the more stable a carbocation is, the more likely it is to form -> leads to major and minor products in some electrophilic addition
