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

Options:

Correct Answer: Higher

Solution:

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

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

Step 1: Understand what amines and alkanes are. Amines are organic compounds that contain nitrogen, while alkanes are hydrocarbons made only of carbon and hydrogen.
Step 2: Learn about boiling points. The boiling point is the temperature at which a substance changes from a liquid to a gas.
Step 3: Know that hydrogen bonding is a strong type of attraction that occurs when hydrogen is bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine.
Step 4: Recognize that amines can form hydrogen bonds because they contain nitrogen, which can bond with hydrogen atoms from other amine molecules.
Step 5: Understand that alkanes cannot form hydrogen bonds because they only contain carbon and hydrogen, which do not have the same strong attractions.
Step 6: Conclude that because amines can form hydrogen bonds, they have higher boiling points than alkanes, which cannot.
