Question: What is the effect of increasing the carbon chain length on the boiling point of aldehydes?

Options:

Correct Answer: Increases

Solution:

The boiling point of aldehydes increases with the increase in carbon chain length due to increased van der Waals forces.

What is the effect of increasing the carbon chain length on the boiling point of aldehydes?

Correct Answer: Boiling point increases with carbon chain length.

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: Learn about carbon chain length. The carbon chain length refers to the number of carbon atoms in the molecule.
Step 4: Recognize that as the carbon chain length increases, there are more carbon atoms in the aldehyde.
Step 5: Understand that more carbon atoms mean more surface area for interactions between molecules.
Step 6: Identify that these interactions are called van der Waals forces, which are weak attractions between molecules.
Step 7: Realize that stronger van der Waals forces require more energy to overcome, leading to a higher boiling point.
Step 8: Conclude that as the carbon chain length increases, the boiling point of aldehydes increases due to stronger van der Waals forces.
