Does RbF or CO2 have a higher boiling point?
The only intermolecular force present is a relatively weak dispersion force (small molar mass). CO2 will have the lowest boiling point. Ion-ion attractions are much stronger than any intermolecular force. RbF has the highest boiling point.
How do you arrange hydrocarbons in order of increasing boiling point?
- The boiling point of the hydrocarbons increases with the increasing molecular mass.
- As molecular mass increases the intermolecular force of attractions (Van der Waal’s force and London force) increases that require a higher amount of energy to break the bond.
- Therefore, the correct order is C3H6
What is the boiling point of RbF?
2,566°F (1,408°C)
Rubidium fluoride/Boiling point
How do you determine the boiling point of a compound?
Intermolecular forces (IMFs) can be used to predict relative boiling points. The stronger the IMFs, the lower the vapor pressure of the substance and the higher the boiling point. Therefore, we can compare the relative strengths of the IMFs of the compounds to predict their relative boiling points.
Why does CH3OH have a higher boiling point?
CH3OH and CH3CH2OH have hydrogen bonds due to the very electronegative O atom bonded to the H atom. These H-bonds are much stronger than the dispersion and dipole-dipole forces in the other compounds and hence these two compounds have the highest boiling points.
What compounds have the highest boiling point?
Propionamide has the strongest intermolecular forces, It should have the highest boiling point.
Which of the following compounds has the highest boiling point?
Propan-1-ol has the highest boiling point because propan-1-ol contains H-bonding in their structure. Hence, Propan – 1 – ol has the highest boiling point amongst the given options. So, the correct answer is option A. Note- The normal boiling point of a compound is an indicator of the volatility of that compound.
Which arrangement shows alkanes with increasing boiling points?
molecular size
Therefore, the boiling points of the alkanes increase with molecular size. Where you have isomers, the more branched the chain, the lower the boiling point tends to be….Boiling Points.
