Dipole/Ion-dipole
Do intermolecular forces have a strong or weak attraction when compared to intramolecular forces?
These forces are weak compared to the intramolecular forces, such as the covalent or ionic bonds between atoms in a molecule.
Is there a strong or weak attraction of hydrogen atoms between the water molecules in a liquid?
Strong attraction
Do dispersion forces have a strong or weak attraction?
Weak attraction
What are intermolecular forces?
Intermolecular forces are the forces of attraction or repulsion which act between neighboring particles (atoms, molecules, or ions).
What SI Class do I teach
Chemistry II
Between what type of molecules do dipole interactions occur?
Diatomic molecules
Hydrogen bonding is a type of
Strong dipole-dipole intermolecular force
When do LDFs occur?
Between all molecules. Most importantly between nonpolar molecules.
Are intermolecular forces stronger or weaker than intramolecular forces?
Intermolecular forces are weaker than intramolecular forces, because the attractions that hold compounds together are stronger than the attractions between molecules.

When do dipole-dipole forces occur?
Between polar molecules.
They occur when the slightly positive end of one polar molecule is attracted to the slightly negative end of another polar molecule.
When do hydrogen bonds occur?
These occur between polar covalent molecules that possess a hydrogen atom bonded to an extreme electronegative element (N, O, F)
At room temperature, F2 and Cl2 are gases, Br2 is a liquid, and I2 is a solid. This is because:
Dispersion interactions increase with molecular size
What are three types of intermolecular forces from strongest to least strongest?
Hydrogen Bonding > Dipole-dipole > LDFs
What is my Classification
Junior
What intermolecular force is responsible for the attraction between an ion and a polar molecule?
Ion-dipole interaction
Where are the strongest hydrogen bonds?
Between molecules containing F-H bonds
Based on the following information: CF4, Molecular Weight 87.99, Normal Boiling Point -182°C CCl4, Molecular Weight 153.8, Normal Boiling Point -123°C The intermolecular forces of attraction in the above substances is described by which of the following:
Dispersion forces
What happens to the vapor pressure as the intermolecular forces increase?
The stronger the intermolecular forces, the lower the vapor pressure.

Does an ion-dipole have a strong or weak attraction?
Ion-dipole has a strong attraction
What effect does H-bonding have on the properties of the substance?
Hydrogen bonding leads to substantial increases in physical properties such as the expected boiling/melting points.
What happens to the LDFs when the molecule is bigger?
The boiling point of CH4 is much lower than that of HF. This is because:
Of hydrogen bonding in HF
