Pearson Edexcel IAL Chemistry AS 3.15 Polar bonds & polar molecules

Pearson Edexcel IAL Chemistry AS 3.15 Polar bonds & polar molecules
Pearson Edexcel IAL Chemistry syllabusChemistry YCH11First assessment 2019

Practise deciding whether molecules are polar by combining bond polarity, molecular shape, symmetry and experimental behaviour.

How this is tested

  • predict molecular polarity from shape and symmetry in species
  • distinguish polar bonds from a permanent molecular dipole when dipoles cancel
  • use liquid-deflection or intermolecular-force evidence to identify polar and non-polar molecules
