Electrophillic Addition

Question 1

What does electrophilic addition show?

Answer 1

Shows how electrophiles attack the double bond in alkenes

Question 2

What are electrophiles?

Answer 2

Electron acceptors
Which are attracted to areas of high electron density

Question 3

What can electrophiles form from alkenes?

Answer 3

• alkyl hydrogensulphates
• halogenoalkanes from alkenes

Question 4

Give examples of the most common electrophiles

Answer 4

HBr
Br2
H2SO4

Question 5

In electrophilic addition, what happens when the carbon-carbon double bond is broken

Answer 5

Carbocation forms
( Carbon atoms with only three bonds, meaning it has a positive charge)

Question 6

Describe carbocations in terms of stability

Answer 6

• carbocations can have varying stability
• with tertiary being the most table and primary being the least
• the more stable the carbocation, the more likely it is to form
• in electrophilic addition multiple products can form
• but the major product is most stable
