Understanding Ozonolysis of Alkenes

What is the primary purpose of using ozone in the ozonolysis of alkenes?

• To add hydrogen atoms

• To break the alkene double bond

• To form a polymer

• To reduce the alkene

What is the unstable compound formed initially during the ozonolysis of ethene?

• Ozonoid

• Acetaldehyde

• Formaldehyde

• Molozonoid

What role does zinc play in the ozonolysis reaction?

• It adds to the alkene

• It forms zinc oxide with oxygen

• It reduces the alkene

• It acts as a catalyst

What is the main difference between molozonoid and ozonoid compounds?

• Both are unstable

• Both are stable

• Molozonoid is unstable, ozonoid is stable

• Molozonoid is stable, ozonoid is unstable

What is the first step in the trick to solve ozonolysis problems?

• Identify the single bonds

• Add water to the reaction

• Add zinc to the reaction

• Locate the double bond in the alkene

What are the products when propane undergoes ozonolysis?

• Methanol and ethanol

• Propane and butane

• Acetaldehyde and formaldehyde

• Acetone and methanol

Which compound is formed when an alkene is converted to a ketone using ozonolysis?

• Propane

• Ethanol

• Methanol

• Acetone

What is the final product when benzene undergoes ozonolysis under special conditions?

• Acetone

• Glycol

• Acetaldehyde

• Formaldehyde

How many grexole compounds are formed from benzene during ozonolysis?

• Four

• Three

• Two

• One

What is the key condition for converting benzene to glycol using ozonolysis?

• Low pressure

• Presence of a catalyst

• Special conditions

• High temperature
