Borek said:What kinds of intermolecular bonds/interactions/forces do you know?
Borek said:Which is stronger? And which apply to which of these molecules?
Sall1230 said:does that mean that alcohols always have higher boiling points than ketones/aldehydes regardless of their molecular weight?
The boiling point of a substance is determined by its intermolecular forces, specifically the strength of its hydrogen bonds, dipole-dipole interactions, and London dispersion forces. The stronger these forces are, the higher the boiling point will be.
Yes, generally as the molecular weight of a substance increases, so does its boiling point. This is because larger molecules have more electrons and a larger surface area, which leads to stronger intermolecular forces.
The boiling point of a substance is not only determined by intermolecular forces, but also by the shape and structure of its molecules. Even substances with similar molecular weights can have different boiling points if their molecules are arranged differently.
Yes, the boiling point of a substance can change depending on external factors such as pressure and temperature. For example, increasing pressure can raise the boiling point of a substance, while decreasing pressure can lower it.
Yes, there are some substances that have higher boiling points than predicted by their intermolecular forces. This is due to the presence of hydrogen bonding, which is a very strong intermolecular force that can significantly increase the boiling point of a substance.
