Match each hydrocarbon trend in crude oil with its correct description: Viscosity | Increases with increasing molecular size due to greater intermolecular attractions. Flammability | Decreases with increasing molecular size due to higher energy needed for vaporization. Boiling Point | Increases with increasing molecular size due to stronger van der Waals forces.
Understand the Problem
The question asks to match hydrocarbon trends in crude oil (viscosity, flammability, and boiling point) with their correct descriptions related to molecular size and intermolecular forces. Essentially, it's testing your understanding of how these properties change as hydrocarbon molecules get larger.
Answer
* Viscosity increases with molecular size. * Flammability decreases with molecular size. * Boiling Point increases with molecular size.
Here's the matching of hydrocarbon trends in crude oil with their descriptions:
- Viscosity: Increases with increasing molecular size due to greater intermolecular attractions.
- Flammability: Decreases with increasing molecular size due to higher energy needed for vaporization.
- Boiling Point: Increases with increasing molecular size due to stronger van der Waals forces.
Answer for screen readers
Here's the matching of hydrocarbon trends in crude oil with their descriptions:
- Viscosity: Increases with increasing molecular size due to greater intermolecular attractions.
- Flammability: Decreases with increasing molecular size due to higher energy needed for vaporization.
- Boiling Point: Increases with increasing molecular size due to stronger van der Waals forces.
More Information
The properties of hydrocarbons, such as viscosity, flammability, and boiling point, are directly related to their molecular size and the intermolecular forces between the molecules.
Tips
Students may confuse the relationship between molecular size and flammability, mistakenly thinking larger molecules are easier to ignite. However, larger molecules require more energy to vaporize, thus decreasing flammability.
