Intermolecular Forces

Question 1

Intermolecular forces

Answer 1

Weak forces between molecules. Caused by attractive forces between very small dipoles
- permanent dipole-dipole
-van der waal
-hydrogen bonds

requiers energy , drawn as //// or IIII between molecules

Question 2

Intramolecular forces

Answer 2

Forces between atoms
-covalent bonds
-ionic bonds
Very strong

Question 3

Dipole

Answer 3

någonting med två olika laddningar, tex en molekyl som H20

Question 4

Instantaneous Dipole-induced Dipole

Answer 4

Van der Waal bond.
When an instanteneous dipole induces/causes another dipole in another molecule.
The e- move to one side => slight charge => slight intermolecular force (causes the e- on the other molecule to be repelled -> dipole)

Very weak because e- move around all the time, which also causes it to happen in all molecules.
The amount e- determine strength of van der waal (more= stronger)

Question 5

Boiling Points

Answer 5

When boiling something you area breaking intermolecular forces (so it can become fristående, gass)

Question 6

Hydrogen Bonds

Answer 6

Formed by attraction betweeen δ+ & δ-
Occurs in O-H, N-H and sometimes F-H bonds

tex water: becuase there are lone pairs with δ- charge there becomes an atomic charge between H and O due to H being δ+ (H could become neutral with the O lone pair)
