What is the strongest intermolecular force in HF?
hydrogen- bonding interaction
Comments to the instructor: The strongest intermolecular force for HF is the hydrogen- bonding interaction. This is a stronger force than the dipole-dipole interactions between HI, HBr and HCl.
What is the intermolecular force between HF?
The figure above shows the hydrogen bonding intermolecular attractive force between HF molecules in liquid HF. HF is a polar molecule so both dispersion forces and dipole-dipole forces are present.
What kind of force is between two HF molecules?
A good example is HF (this is also an example of a special type of dipole-dipole force called a hydrogen bonding).
Does HF have strong dispersion forces?
In order of increasing boiling point: HCl, HBr, HI, HF. The trend is determined by strength of dispersion force which is related to the number of electrons, except for HF, which exhibits hydrogen bonding sufficiently strong to more than compensate for the smaller number of electrons in the HF molecule.
Which liquid has the strongest intermolecular forces?
Water
Water has the strongest intermolecular forces (hydrogen bonds) of all the substances used.
What type of force that holds Co?
CO has two C-O bonds. The dipoles point in opposite directions, so they cancel each other out. Thus, although CO₂ has polar bonds, it is a nonpolar molecule. Therefore, the only intermolecular forces are London dispersion forces.
What is the strongest intermolecular force in CH2O?
dipole – dipole
CH2O and CH3OH are polar, so their strongest IMF are dipole – dipole; however, CH3OH can hydrogen bond while CH2O cannot so its dipole – dipole forces should be stronger.
Which attractive force is the weakest?
London dispersion force
The London dispersion force is the weakest intermolecular force. The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles. This force is sometimes called an induced dipole-induced dipole attraction.
What force is HF?
HF is a polar molecule: dipole-dipole forces. Hydrogen is bounded to F. Hydrogen bonds exist. There are also dispersion forces between HBr molecules.
