Arrange the following in order of increasing boiling point: rbf, co2, ch3oh, ch3br. explain your reasoning.

The following is the order from lowest boiling point to highest based on the types of forces these compounds have: CO2 CH3Br CH3OH RbF CO2 is a nonpolar molecular compound. The only intermolecular force present is a relatively weak dispersion force, because of the small molar mass. CO2 will have the lowest boiling point. ď‚· CH3Br is a polar molecule. Dispersion forces (present in all matter) and dipoleâ’dipole forces will be present. This compound has the next highest boiling point. ď‚· CH3OH is a polar molecule, which can form hydrogen bonds; these are especially strong dipole-dipole attractions. Dispersion forces and hydrogen bonding are present to give this substance the next highest boiling point. ď‚· RbF is an ionic compound. Ionâ’ion attractions are much stronger than any intermolecular force. RbF has the highest boiling point

We can arrange the given compound in order of increasing boiling point as CO2 <CH3Br <CH3OH <RbF.

The compound with the highest boiling point is RbF, since it has the strongest intermolecular force.

CH3OH, CH3Br can doesn't posses strong intermolecular force compare to RbF, and they can form hydrogen bond.

CO2 can form weak dispersion force and it's a non polar compound and it posses the boiling point.

What is boiling point?

This is the temperature at whereby the vapor pressure of a liquid equals the pressure.

At this temperature, the liquid changes into a vapor and the weaker the force of attraction the lower the boiling point.
