Question: What is the boiling point trend of alcohols compared to alkanes?

Options:

Correct Answer: Higher

Solution:

Alcohols have higher boiling points than alkanes due to hydrogen bonding.

What is the boiling point trend of alcohols compared to alkanes?

What is the boiling point trend of alcohols compared to alkanes?

Step 1: Understand what boiling point means. It is the temperature at which a liquid turns into a gas.
Step 2: Know that alcohols and alkanes are both types of organic compounds.
Step 3: Recognize that alcohols contain a hydroxyl group (-OH) which allows them to form hydrogen bonds.
Step 4: Understand that hydrogen bonds are strong attractions between molecules, which require more energy to break.
Step 5: Compare this to alkanes, which do not have hydrogen bonding and only have weaker van der Waals forces.
Step 6: Conclude that because alcohols can form hydrogen bonds, they have higher boiling points than alkanes.
