Question: What is 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).

How do you know which has the highest boiling point?

Consider the boiling points of increasingly larger hydrocarbons. More carbons means a greater surface area possible for hydrophobic interaction, and thus higher boiling points. As you would expect, the strength of intermolecular hydrogen bonding and dipole-dipole interactions is reflected in higher boiling points.

Which has the highest boiling point *?

Among the given noble gases Xenon has the highest boiling point.

Which material has the highest boiling point?

Boiling Point: It is defined as the temperature at which a liquid changes into a gas. Tungsten (W) is the metal (in pure form) with the highest melting point with a melting point of 3695 K (3410°C) Also, with a boiling point of 6203 K, Tungsten has the highest boiling point of all metals.

Which molecule has the highest melting point?

Tungsten (W) is the metal (in pure form) with the highest melting point with a melting point of 3695 K (3410°C) Also, with a boiling point of 6203 K, Tungsten has the highest boiling point of all metals.

Which functional group has highest boiling point?

Lesson Summary

  • Ethers have a higher boiling point than alkanes because they have both London dispersion forces and dipole-dipole interactions.
  • Amines have a higher boiling point than both ethers and alkanes because they have London dispersion forces, dipole-dipole attractions, and hydrogen bonding.

Which has higher boiling point he or AR?

Because of larger size the outer electrons are less tightly held in the larger atoms so that instantaneous dipoles are more easily induced resulting in greater interaction between argon atoms. Therefore, its boiling point (-108.1 °C) is more than that of Helium.

Which element has the highest boiling point? A. He. B. Ne. C. Kr. D. Xe.

Element Atomic Number
Krypton 36
Xenon 54

Which has a higher boiling point H2O or NH3?

Each H2O molecule possesses 2 lone pairs on O and 2 H. H2O molecules are thus able to form an average of 4 H-bonds. H2O has a higher boiling point than NH3 because (i) the H-bonds are stronger and (ii) it contains twice as many H-bonds.

Which one has the highest and lowest boiling point?

Helium has the lowest boiling point of all the elements at –452.074°F (–268.93°C) followed by hydrogen –423.16°F (–252.87°C). According to the CRC Handbook of Chemistry and Physics, the highest boiling point for an element is that of rhenium 10,104.8°F (5,596°C) followed by tungsten 10,031°F (5,555°C).

Which non metal has the highest boiling point?

The non-metal, carbon in diamond form, is the hardest substance due to the strongest interaction among the carbon atoms. Hence, it is carbon in diamond form which has very high melting and boiling points.
