CH3CH2OH has the strongest intermolecular forces because it has the strongest dipole–dipole forces due to hydrogen bonding.
What type of intermolecular force is CH3CH2OH?
Only dispersion forces are present and these are largest in the longer chain alkane as it has more electrons (more bonds). Both molecules possess dipole moments but CH3CH2OH contains hydrogen bonded to an electronegative element so H-bonding is possible.
What is the strongest intermolecular force in ethanol?
Ethanol has an OH group (O bonded to H) which means that it can form hydrogen bonds between molecules. Hydrogen bonding is the strongest type of intermolecular force, therefore ethanol has the highest boiling point.
What intermolecular forces are shared between CH3CH2OH and CH3CH2NH2?
The intermolecular forces of attraction between CH3CH2NH2 are dispersion forces and hydrogen bonds. Dispersion forces are due to the ethyl ends of the molecule and the hydrogen bonds are due to the presence of the amine end of the molecule.
What is the strongest intermolecular force in CH3OH?
c) CH3OH – Hydrogen bonding CH3SH – Dipole-dipole interaction Hydrogen bonding is the strongest intermolecular force, so CH3OH will have the higher boiling point.
Which is the strongest intermolecular force?
Dipole-dipole interactions are the strongest intermolecular force of attraction.
Which compound has the strongest intermolecular forces?
The strongest intermolecular force is hydrogen bonding, which is a particular subset of dipole-dipole interactions that occur when a hydrogen is in close proximity (bound to) a highly electronegative element (namely oxygen, nitrogen, or fluorine).
What is the weakest intermolecular 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.
What is the strongest intermolecular force in CCl4?
Intermolecular forces in CCl4
- The C-Cl bonds are polar but, because of the tetrahedral symmetry, the bond dipoles cancel each other.
- Thus, CCl4 is a nonpolar molecule, and its strongest intermolecular forces are London dispersion forces.

What is the strongest intermolecular force in methane?
Therefore the strongest intermolecular forces between CH4 molecules are Van der Waals forces. Hydrogen bond are stronger than Van der Waals forces therefore both NH3 and H2O will have higher boiling points than CH4.
What is the main intermolecular force in pf3?
CH3OCH3 will have the higher vapor pressure. Vapor pressure tends to decrease as the strength of the intermolecular forces increase. CH3OH can hydrogen bond. CH3OCH3 is polar (bent shape around the oxygen), so dipole-dipole forces are the strongest forces in this compound.
What is the strongest type of intermolecular force present in ethylamine CH3CH2NH2?
What is the major intermolecular force at work in ethylamine, CH3CH2NH2? Hydrogen Bonding – Ethylamine is a polar molecule with a hydrogen covalently bonded to a N. So while it has dispersion forces, and dipole-dipole forces at work it also has hydrogen-bonding capability.
What intermolecular forces are shared between ch3f and CF4?
CF4 : London dispersion forces.
What type of intermolecular force is methanol?
Methanol molecules form dipole-dipole interactions between the partially positive hydrogen and the partially negative oxygen. This bond is also called a hydrogen bond. Hydrogen bonds are an extreme type of a dipole-dipole interaction.
What is the strongest intermolecular force in h2?
Hydrogen Bonding (H-Bonding)
They only occur between hydrogen and oxygen, fluorine or nitrogen, and are the strongest intermolecular force.
Does acetone have dipole-dipole forces?
Acetone has a dipole, so dipole-dipole forces will be present. Water has a dipole and can also hydrogen bond, as can isobutyl alcohol.
