Definition of unfamiliar molecules
Check what you remember
Read the wording for your board, then hide it and explain unfamiliar molecules in your own words. Rough notes are fine. This is a self-check, with no mark or grade.
Reference: AQA
For a molecule that is not familiar, work from the structure to judge the size of the induced dipole-dipole forces from the number of electrons and the shape.
