IMFs

What is NOT a type of intermolecular force

• Ionic or covalent bonding within atoms

• Hydrogen bonding between atoms

• London Dispersion forces between atoms

• Dipole-dipole forces between atoms

Answer explanation

Ionic or covalent bonding within atoms is not an intermolecular force because it occurs within the atom, not between atoms.

(2 answers) What Intermolecular force is between 2 polar molecules?

• Ionic bonding in the molecules

• Hydrogen bonding between molecules

• London Dispersion force between molecules

• Dipole dipole forces between molecules

Answer explanation

Intermolecular forces between two polar molecules include hydrogen bonding and dipole-dipole forces, making them the correct choices.

What is the strongest IMF?

• Hydrogen bonding

• Dipole dipole forces

• London Dispersion forces

• Covalent bonding

Answer explanation

Hydrogen bonding is the strongest IMF due to the high electronegativity difference between hydrogen and other atoms, leading to a strong dipole-dipole interaction.

What is the weakest IMF?

• Hydrogen bonding

• Dipole dipole forces

• London Dispersion forces

• Covalent bonding

Answer explanation

London Dispersion forces are the weakest IMF among the options provided.

INTRAmolecular forces are

• Forces between the molecules that connect them together

• Forces that hold the molecule together

• I have never heard of that word in my life and I am going to self sabotage and pick this to get a few giggles

Answer explanation

The correct answer is 'Forces that hold the molecule together.' INTRA refers to within, so intramolecular forces are the forces that keep the atoms within a molecule bonded together.

London dispersion forces happen between what types of molecules?

• Between non polar molecules

• Between polar molecules

Answer explanation

London dispersion forces occur between non polar molecules due to temporary fluctuations in electron distribution.

Dipole dipole forces happen between what types of molecules?

• Between non polar molecules

• Between polar molecules

Answer explanation

Dipole-dipole forces occur between polar molecules, where there is an unequal distribution of charge leading to partial positive and negative ends.

Hydrogen bonding is a very specific type of Intermolecular force. Which aspect of this picture represents that?

• The bond that is in solid black that is the bond within the water molecule keeping it together

• The bond that is bright green, which is between the 2 water molecules

Answer explanation

The bright green bond between the 2 water molecules represents hydrogen bonding, a specific type of intermolecular force.

(multiple answers) For it to count as hydrogen bonding between molecules, it has the be a H bonded to a

• Flourine (F)

• Oxygen (O)

• Nitrogen (N)

• Carbon (C)

Answer explanation

Hydrogen bonding between molecules requires a hydrogen atom bonded to Fluorine (F), Oxygen (O), or Nitrogen (N).

There are many types of intermolecular forces (IMF), and molecules go through them at different times.

However, which IMF would be the strongest between these molecules?

• London dispersion forces

• Dipole-dipole forces

• Hydrogen bonding

• Ionic forces
