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.
