# How do you know what has a higher boiling point?

Contents

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.

## What makes something have a high boiling point?

The boiling point of a liquid depends on the intermolecular forces present between the atoms or molecules in the liquid since you must disrupt those forces to change from a liquid to a gas. The stronger the intermolecular forces, the higher the boiling point.

## How do you determine boiling point?

The Formula for Boiling Point

It are often calculated as: Kb = RTb2M/ΔHv, R is that the universal gas constant. Tb is that the boiling temperature of the pure solvent [in K] M is that the molar mass of the solvent.

## Which compound would have the highest boiling point?

Among the given options, (c) ethanol has the highest boiling point as it has the strongest intermolecular force of hydrogen bonding.

## Which substance is expected to have the highest boiling point?

HF has the highest boiling point.

## Which of the following substances has the highest melting point?

Tungsten is the chemical element with the highest melting point at \$ 3,{414^o}C \$ . This property makes tungsten use as electrical filaments in incandescent lamps.

## Which substance is expected to have the highest boiling point quizlet?

The boiling point is the temperature at which a substance will change from the liquid phase to the gas phase, so compounds with stronger intermolecular forces will have higher boiling points. HF can form hydrogen bonds. Therefore, HF will have the strongest intermolecular forces and thus the highest boiling point.

## Which atomic solid has the highest melting point?

The chemical element with the lowest melting point is Helium and the element with the highest melting point is Carbon.
