Question: Which carboxylic acid has the highest boiling point?

Options:

Correct Answer: Butanoic acid

Solution:

Butanoic acid has the highest boiling point due to its longer carbon chain.

Which carboxylic acid has the highest boiling point?

Which carboxylic acid has the highest boiling point?

Step 1: Understand what carboxylic acids are. They are organic compounds that contain a carboxyl group (-COOH).
Step 2: Know that boiling point is the temperature at which a liquid turns into vapor.
Step 3: Recognize that the boiling point of carboxylic acids can be influenced by the length of their carbon chain.
Step 4: Identify the carboxylic acids being compared. In this case, we are looking at butanoic acid and possibly others.
Step 5: Understand that longer carbon chains generally lead to higher boiling points because they have more surface area for intermolecular forces.
Step 6: Conclude that butanoic acid, having a longer carbon chain compared to shorter carboxylic acids, has the highest boiling point.
