IB Chemistry - Bonding

IB Chemistry home > Syllabus 2025 > Structure and bonding > Polarity

The term 'polarity' refers to a separation of electrical charge. This chapter examines how this separation can come about and its consequences in molecules.

Structure 2.2.5 - Bond polarity results from the difference in electronegativities of the bonded atoms.

  • Deduce the polar nature of a covalent bond from electronegativity values.


  • Bond dipoles can be shown either with partial charges or vectors.
  • Electronegativity values are given in the data booklet.
