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 intermolecular force is in HF?
Intermolecular Forces
HF is a polar molecule: dipole-dipole forces. Hydrogen is bounded to F. Hydrogen bonds exist. There are also dispersion forces between HBr molecules.
What has the strongest intermolecular force?
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).
Which type of force of attraction exist in HF?
Answer. The intermolecular forces present between HF molecules are mainly dipole interaction and Hydrogen bonds.
What is the strongest intermolecular force in C3H8?
b) C3H8 – London-dispersion force CH3OCH3 –Dipole-dipole The higher boiling point belongs to CH3OCH3 because is has the stronger intermolecular force, dipole-dipole interaction.
What is the strongest intermolecular force in acetone?
Acetone has a dipole, so dipole-dipole forces will be present. Water has a dipole and can also hydrogen bond, as can isobutyl alcohol. However, isobutyl alcohol is heavier than water, and will thus have the highest boiling point.
Which attractive force is the weakest?
Dispersion forces are the weakest intermolecular force (one hundredth-one thousandth the strength of a covalent bond), hydrogen bonds are the strongest intermolecular force (about one-tenth the strength of a covalent bond).
What are the 3 intermolecular forces from weakest to strongest?
There are three different types of intermolecular forces in terms of strength. They are (strongest to weakest) hydrogen bonding, dipole-dipole and Van der Waals’ forces.
Is HF a hydrogen bond?
Although a diatomic molecule, HF forms relatively strong intermolecular hydrogen bonds. Solid HF consists of zig-zag chains of HF molecules. The HF molecules, with a short H–F bond of 95 pm, are linked to neighboring molecules by intermolecular H–F distances of 155 pm.
Is hydrogen bonding the strongest intermolecular force?
Hydrogen bonds are strong intermolecular forces created when a hydrogen atom bonded to an electronegative atom approaches a nearby electronegative atom. … The hydrogen bond is one of the strongest intermolecular attractions, but weaker than a covalent or an ionic bond.
Does HF have a dipole moment?
Note that each hydrogen halide (HF, HCl, HBr, and HI) has a significant dipole moment. Moreover, the dipole moments increase as we move up the periodic table in the halogen group. We can conclude that fluorine atoms have a greater electronegativity than do chlorine atoms, etc.
What is the strongest intermolecular force in Cl2?
What type of intermolecular forces exist between cl2 and CCl4?
| Question | Answer |
|---|---|
| What is the strongest type of intermolecular force present in Cl2? | Dispersion |
| What is the strongest intermolecular force present in CHBr3? | dipole-dipole |
| What type of intermolecular force causes the dissolution of KF in water? | ion-dipole force |
What is the strongest intermolecular force to be over 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.
Which substance has the weakest intermolecular force?
- Oil- Only London Dispersion Forces (the weakest intermolecular force)
- Water- London Dispersion, Dipole-Dipole, and Hydrogen Bonding.
