Chapter 6.5: Oxidation

Question 1

What is the loss of electrons?

Answer 1

oxidation

Question 2

Define reduction

Answer 2

gain of electrons

Question 3

What is OsO4 used for?

Answer 3

oxidation of an alkeen to a glycol

Question 4

Define oxidation

Answer 4

loss of electron

Question 5

Describe the mechanism of ozonolysis (oxidation of an alkene)

Answer 5

• Ozone-Cleavage of a Carbon-Carbon Double Bond (Ozonolysis)
o Step 1: Ozone reacts with the alkene with both electrophilic and nucleophilic character in a single, simultaneous step
o Step 2: Break a bond to give stable molecules or ions
o Step 3: Reduction of the ozonide and cleavage results in the final carbonyl fragments

Question 6

What is the gain of electrons?

Answer 6

reduction
