Questions & Step-by-Step Solutions
Which of the following statements about alkynes is true?
Step 1: Understand what alkynes are. Alkynes are hydrocarbons that contain at least one triple bond between carbon atoms.
Step 2: Know what alkenes are. Alkenes are hydrocarbons that contain at least one double bond between carbon atoms.
Step 3: Learn about boiling points. The boiling point of a substance is the temperature at which it changes from a liquid to a gas.
Step 4: Recognize that stronger intermolecular forces lead to higher boiling points. Intermolecular forces are the forces that hold molecules together.
Step 5: Compare the types of bonds in alkynes and alkenes. Alkynes have triple bonds, which create stronger intermolecular forces compared to the double bonds in alkenes.
Step 6: Conclude that because alkynes have stronger intermolecular forces due to their triple bonds, they have a higher boiling point than alkenes.
