New cards

what are london forces

instantaneous dipole induced dipole forces

THEY ALWAYS EXIST IN MOLECULES

2
New cards

how are they produces

electrons are constantly moving fast in orbitals

theres a chance of one side having more electrons than the other which produces a dipole

the dipole induces dipoles on nearby atoms

3
New cards

effect of the number of electrons on the mp of london forces

more electrons = bigger instantaneous dipole = stronger attraction = more energy required to seperate particles

4
New cards

why are london forces the weakest IMF

the dipoles are not constant and thus are instantaneous
