Organic Chemistry Addition Reactions

What organic chemical found in black pepper is responsible for its spicy taste?

• Capsaicin

• Piperine

• Curcumin

• Menthol

In an addition reaction involving alkenes, what happens to the double bond?

• It breaks and forms two new single bonds

• It becomes a triple bond

• It remains unchanged

• It forms a ring structure

What term describes a reaction's tendency to bond groups to one atom over another in an asymmetrical molecule?

• Stereoselectivity

• Chemoselectivity

• Regioselectivity

• Enantioselectivity

In a halogenation reaction, if the added groups attach to opposite sides of the double bond, what type of addition is it?

• Syn addition

• Anti addition

• Markovnikov addition

• Hydration

What is the expected stereochemistry of the added groups in halohydrin formation?

• Syn-addition

• Anti-addition

• Both syn and anti

• No specific stereochemistry

Which type of reaction can involve carbocation rearrangements?

• Halohydrin formation

• Oxymercuration

• Acid-catalyzed hydration

• Hydroboration

What is a key characteristic of oxymercuration/reduction that prevents certain shifts?

• It always results in syn-addition

• It uses a strong acid catalyst

• It blocks carbocation rearrangements

• It adds to the less substituted carbon

In hydroboration, where does the hydroxyl group (OH) typically add to the double bond?

• To the more substituted carbon

• To the less substituted carbon

• Randomly to either carbon

• Only to primary carbons
