Question: What is the effect of increasing the number of carbon atoms in aldehydes on their boiling points?

Options:

Correct Answer: Increases

Solution:

The boiling points of aldehydes increase with the number of carbon atoms due to increased van der Waals forces.

What is the effect of increasing the number of carbon atoms in aldehydes on their boiling points?

Step 1: Understand what aldehydes are. Aldehydes are organic compounds that contain a carbonyl group (C=O) at the end of a carbon chain.
Step 2: Know that boiling point is the temperature at which a liquid turns into a gas.
Step 3: Recognize that the number of carbon atoms in an aldehyde affects its size and mass.
Step 4: Learn about van der Waals forces. These are weak attractions between molecules that increase with larger molecules.
Step 5: Realize that as the number of carbon atoms increases, the size of the aldehyde increases, leading to stronger van der Waals forces.
Step 6: Conclude that stronger van der Waals forces require more energy to overcome, which raises the boiling point.
