A
Electron-poor sites
5
Q
What are nucleophiles ?
A
- Molecules or ions with a lone pair of elctrons that can form a new covalent bond
- Ragentsthat attach molecules that have an electron deficiency
- They are nucleus loving
6
Q
what are electrophiles ?
A
- Molecules or ions that can accept a pair of elctrons during the formation of a new covalent bond
- They are “electron-loving” ragents. They are attracted to parts of molecules that are rich in electrons

7
Q
How do radicals form a bond ?
there are 2 ways
A
- Each free radical donates oe electron to form a two-electrons bond
- Two ions with unlike charges can come together, with the negatively charged ion donating both electrons to form the resulting two-electron bond
