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

Explanation: Boiling point is highly dependent on the intermolecular forces of a compound. Compounds with stronger intermolecular forces, larger masses, and less branching will have higher boiling points.

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

First there is molecular size. 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.

What compound tends has the highest boiling point?

In ionic compounds, there exists a strong force of attraction between the oppositely charged ions, so a large amount of energy is required to break the strong bonding force between the ions. That is why ionic compounds have high melting and boiling point.

How do you tell which compound will have the highest melting point?

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

Which compound will have 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).

Which has highest melting point?

The metal 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.

What is a high boiling point?

A liquid at high pressure has a higher boiling point than when that liquid is at atmospheric pressure. For example, water boils at 100 °C (212 °F) at sea level, but at 93.4 °C (200.1 °F) at 1,905 metres (6,250 ft) altitude. For a given pressure, different liquids will boil at different temperatures.

How do you determine the boiling point of a compound?

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.

Why does ionic compounds have high boiling point?

Ionic compounds are held together by strong electrostatic forces of attraction between oppositely charged ions. These compounds have high melting points and high boiling points because of the large amounts of energy needed to break the many strong bonds. … These bonds between atoms are strong.

Which ionic compound has the highest melting point?

The greater the charge on the ions, the stronger the forces holding them together. Sodium chloride is made from Na + ions and Cl ions and has a melting point of 801°C. Magnesium oxide is made from ions with two charges (Mg 2+ and O 2) and so has a much higher melting point of 2852°C.
