How can one determine the boiling points of compounds?
The boiling points of compounds can be determined by considering the strength of the intermolecular forces between molecules. Compounds with stronger intermolecular forces, such as hydrogen bonding or dipole-dipole interactions, tend to have higher boiling points. Additionally, the size and shape of the molecules can also affect the boiling point. By analyzing these factors, one can predict and compare the boiling points of different compounds.
Do isomers boiling points increase or decrease with more branching?
Generally, the boiling points of isomers decrease with increased branching. This is because increased branching reduces the surface area available for intermolecular forces to act on, resulting in weaker van der Waals forces between molecules. As a result, the molecules are easier to separate, leading to lower boiling points.
What is the boiling points of a hydrogen bond?
Hydrogen bonds themselves do not have boiling points, as they are not substances that can boil. However, the strength of hydrogen bonds influences the boiling points of substances that form hydrogen bonds. Stronger hydrogen bonding generally leads to higher boiling points, as more energy is required to overcome the intermolecular forces holding the molecules together.
Do alcohols have higher boiling points compared to other substances?
Yes, alcohols generally have higher boiling points compared to other substances due to the presence of hydrogen bonding between alcohol molecules.
Why is there a difference in boiling points between h2o and h2s?
The difference in boiling points between water (H2O) and hydrogen sulfide (H2S) is primarily due to differences in molecular structure and intermolecular interactions. Water molecules form stronger hydrogen bonds compared to hydrogen sulfide molecules, leading to a higher boiling point for water. Additionally, water molecules are more polar compared to hydrogen sulfide molecules, which also contributes to the difference in boiling points.
Does longer hydrocarbon molecules have higher boiling points than short hydrocarbon molecules?
yes

Molecular compounds have relatively high boiling points?
Molecular compounds typically have lower boiling points compared to ionic compounds because of weaker intermolecular forces between molecules. The boiling points of molecular compounds increase with increasing molecular size and polarity. However, they generally have lower boiling points compared to ionic compounds due to the nature of the forces holding the molecules together.
What is the connection between the size of the molecules in the crude oil and their condensing or boiling points?
sa
Do isomers boiling points increase or decrease with more branching?
Generally, the boiling points of isomers decrease with increased branching. This is because increased branching reduces the surface area available for intermolecular forces to act on, resulting in weaker van der Waals forces between molecules. As a result, the molecules are easier to separate, leading to lower boiling points.
Why is acid anhydride having higher boiling point than alkane?
Molecules with dipoles have higher boiling points because they are able to form strong dipole-dipole interactions with other molecules. Alkanes are nonpolar and only have weak London dispersion forces, thus lower boiling points.
What is the boiling points of a hydrogen bond?
Hydrogen bonds themselves do not have boiling points, as they are not substances that can boil. However, the strength of hydrogen bonds influences the boiling points of substances that form hydrogen bonds. Stronger hydrogen bonding generally leads to higher boiling points, as more energy is required to overcome the intermolecular forces holding the molecules together.
Do alcohols have higher boiling points compared to other substances?
Yes, alcohols generally have higher boiling points compared to other substances due to the presence of hydrogen bonding between alcohol molecules.
How is high melting and boiling points related to the structure of the compounds?
The structure of a compound will dictate what intermolecular forces hold the molecules together. The stronger these forces, the higher will be the boiling point.
Why is there a difference in boiling points between h2o and h2s?
The difference in boiling points between water (H2O) and hydrogen sulfide (H2S) is primarily due to differences in molecular structure and intermolecular interactions. Water molecules form stronger hydrogen bonds compared to hydrogen sulfide molecules, leading to a higher boiling point for water. Additionally, water molecules are more polar compared to hydrogen sulfide molecules, which also contributes to the difference in boiling points.
Do isomers have the same boiling point?
Isomers are molecules with the same chemical formula but different structures. Due to their different structures, isomers can have different boiling points.
Why do isomers exhibit variations in their boiling points?
Isomers exhibit variations in their boiling points because of differences in their molecular structures, which affect the strength of intermolecular forces between molecules. These forces determine how easily a substance can transition from a liquid to a gas state, leading to differences in boiling points among isomers.
