Questions & Step-by-Step Solutions
Which of the following is a characteristic property of alkynes?
Step 1: Understand what alkynes are. Alkynes are a type of hydrocarbon that contain at least one triple bond between carbon atoms.
Step 2: Know the difference between alkynes and alkenes. Alkenes have double bonds, while alkynes have triple bonds.
Step 3: Learn about boiling points. Boiling point is the temperature at which a substance changes from a liquid to a gas.
Step 4: Recognize that stronger intermolecular forces lead to higher boiling points. This means that if a substance has stronger forces holding its molecules together, it will require more heat to boil.
Step 5: Compare the intermolecular forces of alkynes and alkenes. Alkynes have stronger intermolecular forces than alkenes because of their triple bonds.
Step 6: Conclude that because alkynes have stronger intermolecular forces, they generally have higher boiling points than alkenes.
