You asked: How do you know what has the highest boiling point?

How do you know what 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.

What makes something have a high boiling point?

Large molecules have more electrons and nuclei that create van der Waals attractive forces, so their compounds usually have higher boiling points than similar compounds made up of smaller molecules. … The attractive forces between the latter group are generally greater.

Which will have the highest boiling point?

The chemical element with the lowest boiling point is Helium and the element with the highest boiling point is Tungsten. The unity used for the melting point is Celsius (C).

Which has highest melting point?

The chemical element with the highest melting point is tungsten, at 3,414 °C (6,177 °F; 3,687 K); this property makes tungsten excellent for use as electrical filaments in incandescent lamps.

Which functional group has the highest boiling point?

Carboxylic acids have higher boiling points than all other functional groups mentioned.

Which compound has the highest boiling point?

Among alkanes, boiling point increases with molar mass. Among isomeric alkanes, branching decreases boiling point. Therefore, n-hexane has highest boiling point among these.

Which has the highest boiling point quizlet?

I2 has the highest boiling point because it has the highest molar mass. Because the halogens are all similar in other ways, you would expect I2 to have the greatest dispersion forces and therefore the highest boiling point (and in fact it does).
