Questions & Step-by-Step Solutions
Which of the following statements about alcohols is correct? (2022)
Step 1: Understand what alcohols are. Alcohols are organic compounds that contain a hydroxyl group (-OH).
Step 2: Know what alkanes are. Alkanes are hydrocarbons that only contain single bonds between carbon atoms.
Step 3: Learn about boiling points. The boiling point is the temperature at which a substance changes from a liquid to a gas.
Step 4: Recognize the role of hydrogen bonding. Hydrogen bonding occurs when a hydrogen atom is attracted to an electronegative atom (like oxygen in alcohols).
Step 5: Compare the boiling points of alcohols and alkanes. Alcohols have higher boiling points than alkanes because they can form hydrogen bonds, while alkanes cannot.
Step 6: Conclude that the statement about alcohols having higher boiling points than alkanes due to hydrogen bonding is correct.
