London forces

Question 1

london forces

Answer 1

when non polar atoms or molecules meet there are fleeting repulsions + attractions between the nuclei of the atoms and surrounding clouds of electrons

Question 2

bigger molecules with large molecules of electrons have ..

Answer 2

higher polarisability

Question 3

Longer, stronger chain hydrocarbons have ..

Answer 3

more london forces and so more energy is needed to over come these forces - boiling point increases

Question 4

Branched hydrocarbons

Answer 4

hydrocarbons with branches means they can’t pack together as close - weakens the london forces between the chains and lowers their boiling points
