How do you know which compound has a higher boiling point?

In general, larger molecules have higher boiling points than smaller molecules of the same kind, indicating that dispersion forces increase with mass, number of electrons, number of atoms or some combination thereof.

How do you know which compound has the highest boiling point?

Compounds with stronger intermolecular forces, larger masses, and less branching will have higher boiling points. Compounds II and III only exhibit intermolecular London dispersion forces, so they would be the two lowest boiling compounds (weakest intermolecular forces).

How do you know which compound has a higher melting point?

In general, the greater the charge, the greater the electrostatic attraction, the stronger the ionic bond, the higher the melting point.

What determines boiling point of a compound?

Types of Molecules: the types of molecules that make up a liquid determine its boiling point. If the intermolecular forces between molecules are: relatively strong, the boiling point will be relatively high. relatively weak, the boiling point will be relatively low.

How do you know which ionic compound has a higher boiling point?

The more energy needed, the higher the melting point or boiling point . Since the electrostatic forces of attraction between oppositely charged ions are strong, their melting and boiling points are high.

Which hydrocarbon has highest boiling point?

Hydrocarbon boiling point is also dependent on the length of the carbon chain, and increases as the length of the chain increases. We can conclude that heptane likely has the highest boiling point of the answer choices, as it does not branch and has the longest carbon chain.

Which element has highest boiling point?

The chemical element with the lowest boiling point is Helium and the element with the highest boiling point is Tungsten.
