Rank the Following Compounds in Decreasing Order of Boiling Point
Boiling point is the temperature at which a liquid changes into a gas. It is an important property in chemistry as it can be used to identify and characterize compounds, as well as to predict their behavior in various applications.
The boiling point of a compound is influenced by several factors, including molecular weight, polarity, and intermolecular forces. Generally, heavier molecules have higher boiling points than lighter molecules, polar molecules have higher boiling points than nonpolar molecules, and molecules with stronger intermolecular forces have higher boiling points than molecules with weaker intermolecular forces.

Boiling Point Analysis
The molecular structure of a compound plays a significant role in determining its boiling point. Molecular weight, polarity, and intermolecular forces are all affected by the molecular structure.
Molecular weight is directly proportional to boiling point. Heavier molecules have more mass, which means they have more kinetic energy and require more energy to overcome the intermolecular forces holding them together. Therefore, heavier molecules have higher boiling points.
Polarity is another important factor that influences boiling point. Polar molecules have a separation of charge, which creates an electrostatic attraction between molecules. This attraction makes it more difficult for polar molecules to separate from each other, resulting in higher boiling points compared to nonpolar molecules.
Intermolecular forces are the forces that act between molecules. The strength of these forces determines the amount of energy required to overcome them and separate the molecules. Stronger intermolecular forces lead to higher boiling points.
Applications
Understanding boiling points has numerous practical applications in various fields, including chemistry, engineering, and medicine.
In chemistry, boiling point data is used to identify and characterize compounds. It can also be used to predict the behavior of compounds in reactions and to design new materials with specific properties.
