They are saturated hydrocarbons.
They can undergo polymerization.
They do not react with electrophiles.
They have a higher boiling point than alkanes.
Questions & Step-by-Step Solutions
Which of the following statements about alkenes is true?
Correct Answer: Alkenes can undergo polymerization due to the presence of a double bond.
Step 1: Understand what alkenes are. Alkenes are hydrocarbons that contain at least one double bond between carbon atoms.
Step 2: Recognize the significance of the double bond. The double bond in alkenes makes them reactive compared to alkanes, which only have single bonds.
Step 3: Learn about polymerization. Polymerization is a chemical process where small molecules (monomers) join together to form a larger molecule (polymer).
Step 4: Connect the double bond to polymerization. The double bond in alkenes allows them to open up and link with other alkene molecules, forming long chains (polymers).
Step 5: Conclude that the statement is true. Since alkenes can undergo polymerization because of their double bond, the statement is correct.
