Physical Properties of Alkanes ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],Dispersion Forces

[object Object],[object Object],Leads to liquids, then solids More compact structure, surface area decreases Less contact between molecules, dispersion forces decrease, so lower boiling point
