Topic 3.1 - Intermolecular Forces and Interpartical Forces

Question 1

Types of Intermolecular Forces

Answer 1

London Dispersion Forces, Dipole - Induced, Dipole - Dipole, Ion - Dipole, and Hydrogen Bonding

Question 2

London Dispersion Forces

Answer 2

Between non-polar molecules

Question 3

What leads to stronger LDFs

Answer 3

Increased polarisability. Bigger electron cloud = more polarisability.

Question 4

Can “LDF” and Van Der Waals Forces be used interchangably

Answer 4

No, LDFs are a TYPE of Van der Waals Forces

Question 5

Dipole - Induced Dipole Interactions

Answer 5

Between a polar and nonpolar molecule, very attractive forces

Question 6

What affects the strength of Dipole - Induced Forces?

Answer 6

The magnitude of the dipole of the polar molecule

Question 7

Dipole - Dipole

Answer 7

Between molecules

Question 8

What affects the strength of Dipole - Dipole Forces?

Answer 8

The magnitude of the dipoles and their relative orientation

Question 9

Ion - Dipole

Answer 9

Present between ions and polar molecules, stronger than dipole - dipole

Question 10

Hydrogen Bonding

Answer 10

When hydrogen bonds with a highly electronegative atom

Question 11

What atoms does hydrogen have to bond with for it to be Hydrogen Bonding

Answer 11

Nitrogen, Oxygen, and Fluoride
