About Eduqas A Level Chemistry 1.4 Bonding

This topic explains how and why atoms bond. Expect VSEPR shapes and comparisons of boiling points.

What you need to know

  • Bond types Ionic, covalent, dative covalent and metallic bonding.
  • Electronegativity Polar bonds and polar molecules.
  • Shapes VSEPR theory: lone pairs repel more than bonding pairs; bond angles of common shapes.
  • Intermolecular forces London dispersion forces, permanent dipole-dipole and hydrogen bonding.

Common mistakes in 1.4 Bonding

  • Saying hydrogen bonds are within a molecule of water.
  • Confusing polar bonds with polar molecules.
  • Getting bond angles wrong for lone pair shapes.

Try three 1.4 Bonding exam-style questions

1. State the shape and bond angle of NH₃. (2 marks)

Show the mark scheme answer

Pyramidal (1), 107° (1).

2. Explain why water has a higher boiling point than H₂S. (2 marks)

Show the mark scheme answer

Water forms hydrogen bonds between molecules (1), which need more energy to overcome than the weaker forces in H₂S (1).

3. Define electronegativity. (1 mark)

Show the mark scheme answer

The ability of an atom to attract the bonding pair of electrons in a covalent bond.

1.4 Bonding FAQs

What does Bonding cover?

Types of bonding, electronegativity, shapes of molecules and intermolecular forces.

Do I need to draw dot-and-cross diagrams?

Yes, for ionic and covalent compounds including dative bonds.

Why is CO₂ non-polar?

It is linear, so the bond dipoles cancel.
