Which compound will most likely have the highest boiling point?
While considering boiling points, the thing one has to analyse is the physical forces within the compound. The strongest force is the electrostatic force. Therefore, ionic compounds will always have higher melting/ boiling points than molecular compounds. So, out of the list, RbF will have the highest boiling points.
Which compound has a higher boiling point and why?
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.
What substances have a high boiling point?
The element carbon has the highest melting point around 4200 degree Celsius this high melting point is found in the carbon allotrope called diamond it is and crystalline allotrope of carbon and it has a perfectly defined the internal crystal structure.and also diamond is one of the hardest substances with hardness in mohs scale as 10 ten .diamond is so hard that it cannot be scratched and diamond can be cut or scratched only by the other diamond or lasers.
Which one has higher boiling point and why?
WATER has the highest boiling point because water is a strong dipole and the molecules are interconnected by hydrogen bonds. PH3 = polar molecule = Dipole-Dipole Forces. H2S = polar molecule = Dipole-Dipole Forces. CH4 = Nonpolar Molecule = London Forces = lowest boiling point. H2O = Hydrogen Bonding = Ion-Dipole Forces = highest boiling point
Which substance 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.
Which substance would be expected to have the highest boiling point quizlet?
The correct answer is: CO has the higher boiling point because it experiences dipole-dipole forces. Marks for this submission: 1.00/1.00. Which molecule below has hydrogen bonding (hint: it may help to look at the lewis structures)? Marks for this submission: 1.00/1.00.
How do you find what has the highest boiling point?
The effect of increasing the pressure is to raise the boiling point. Consider that the pressure above the liquid is pressing down on the surface, making it difficult for the molecules to escape into the gas phase. The more pressure, the more energy is required, so the boiling point is higher at higher pressures.
Does CO2 or CO have a higher boiling point?
The larger the small covalent molecule, the greater the intermolecular bonds, hence higher boiling / melting point. CO2 has 3 atoms involved in the molecule and is therefore larger than O2 that has 2 atoms. Hence, CO2 has a higher boiling / melting point compared to O2.
Which of the following do you expect to have the highest melting point?
Detailed Solution Tungsten has the highest melting point, i.e. 3410.0 °C.
