hydrocarbons

polar or non-polar

non-polar

intermolecular forces

dispersion forces

intermolecular forces of hydrocarbons compared to intramolecular forces

weaker

trend - as HC increases MW and why

BP/MP increase due to increased dispersion forces that attract neighbouring molecules

solubility of HC due to polarity and why

HC are non-polar, don’t dissolve well in water

solubility when there are polar functional groups

solubility can increase

electrical conductivity of HC and why

HC don’t have dipole or ionic charges, therefore don’t conduct electricity

safety of HC due to what forces which make them ____

weak intermolecular forces between HC of low MW make them highly volatile

disposal of HC

wastes collected

temporarily stored until authorised agencies collect them for proper disposal
