What has a higher boiling point ch3f or ch3cl? The actual boiling point of CH3F is -78 °C, the boiling point of CH3Cl is -24 °C, In this case, are dispersion interactions or dipole interactions more important for determining relative boiling points?, Why do you conclude this?
Why does CH3F have a higher boiling point than CH3Cl? CH3Cl has larger dipole moment than CH3F because dipole moment is based on the product of distance and charge, and not just charge alone. Fluorine is more electronegative than chlorine, but, the carbon-fluorine bond is also much shorter than the carbon-chlorine bond: 139 pm vs 178 pm.
Does CH3Cl have the highest boiling point? CH3Cl is a dipole. The dipole-dipole interactions are much stronger than the van der Waals interactions present in methane, so it’s boiling point is much higher. When comparing CH4 to CCl4, the latter has a much higher boiling point due to its larger number of electrons meaning stronger van der Waals forces.
Why does CH3F have a higher boiling point? (b) CH3NH2 and CH3F are both covalent compounds and have polar bonds. The dipole in CH3NH2 can H-bond while that in CH3F cannot. Therefore, CH3NH2 has the stronger interactions and the higher boiling point.

Some small explosions may occur if water gets into cracks in the lava and turns to steam faster than the steam bubbles can escape. The second reason that lava flowing into water produces boiling rather than explosions is the enormous amount of heat that it takes to boil water.

What is the boiling point of methanol and ethanol?
Boiling point of methanol is 338 K and the one of ethanol is 351 K. Boiling point of ethanol is higher because the mole mass of ethanol is higher. With a higher mole mass a molecule has more electrons and more electrostatic interactions.

How does polarity affect melting and boiling points?
Hence, more heat energy is required to break the intermolecular forces present in a polar molecule compared to a nonpolar molecule with comparable molar mass. Therefore, both the boiling point and melting point of a polar compound are higher than a nonpolar compound with a comparable molar mass.
Which molecule has the lowest boiling point?
The one with the weakest IMF will have the lowest boiling point. CH4 has only dispersion forces while all the others have dispersion PLUS either dipole-dipole (HCl, H2S, NH3), and/or hydrogen bonding (NH3). So, CH4 will have the lowest boiling point.
