1
Q
Half curved arrow=
A
Movement of ONE electron
2
Q
Whole curved arrow=
A
Shows the movement of TWO electrons
3
Q
Two types of bond forming:
A
Homolytic and Heterolytic
4
Q
Homolytic bond forming
A
(symmetrical) – one electron from two different atoms pair up to form a bond
5
Q
Heterolytic bond forming
A
(unsymmetrical) – two electrons from one atom form a bond with a second atom
6
Q
Which kind of bond breaking/forming is the most common?
A
Heterolytic, usually with polar covalent bonds
7
Q
More positive, electron poor species
A
Electrophile
8
Q
More negative, electron rich species
A
Nucleophile
9

WITH, WITHOUT
10
Q
When drawing curved arrows, the nucleophile (-)…
A
ALWAYS points toward the electrophile (+)
