Which Compound Has Highest Boiling Point?

In summary, the conversation discusses the boiling points of various compounds and ultimately concludes that CH3—COOH (compound C) has the highest boiling point due to its polarity. However, there is some conflicting information regarding compound E (H2S) and its boiling point. Further research is needed for confirmation.

The Attempt at a Solution


Chose C because is more polar with the 2 oxygens, however, the answer has conflicting answer. It says its E while explaining why its C. Can someone confirm which one is right? Thanks!

1. What is boiling point?

Boiling point is the temperature at which a substance changes from a liquid state to a gas state. It is a physical property that is unique to each compound and is dependent on factors such as intermolecular forces and molecular weight.

2. What is the significance of a compound's boiling point?

The boiling point of a compound can give insight into its physical properties, such as its volatility and potential uses. It can also be used to identify and distinguish between different compounds.

3. How is boiling point measured?

Boiling point is typically measured using a thermometer in a closed system, where the liquid is heated until it reaches its boiling point and starts to vaporize. The temperature at which this occurs is recorded as the boiling point.

4. What factors can affect the boiling point of a compound?

The boiling point of a compound is affected by intermolecular forces, molecular weight, and the presence of impurities. Generally, compounds with stronger intermolecular forces and higher molecular weight will have higher boiling points.

5. Which compound has the highest boiling point?

The compound with the highest boiling point will depend on various factors and cannot be determined without specific context. However, in general, polar compounds like water tend to have higher boiling points than nonpolar compounds like hydrocarbons.
