Definitions Flashcards
1
Q
Explain an SN1 mechanism.
A
Favours tertiary molecules, less powerful nucleophile (eg. water), 2 steps, forms a carbocation.
2
Q
Define a functional group.
A
a group of atoms that determine the chemical or physical properties of a compound.
3
Q
Explain an SN2 mechanism.
A
Favours primary molecules, more powerful nucleophiles, 1 step, forms an intermediate.
4
Q
Explain E1 mechanisms.
A
Favours tertiary, weak base, 2 steps, forms a carbocation.
5
Q
Explain E2 mechanisms.
A
Favours tertiary, strong base, 1 steps, forms a transition state.
6
Q
Define a nucleophile.
A
Electron-rich/negatively charged species that are able to polarise and are attracted to the nucleus
7
Q
Define an electrophile.
A
Electron-deficient/positively charged species that are attracted to electrons
