Bonding
- 132 questions
- 8 subtopics
- Physical chemistry, drawn on by Paper 1 and Paper 2
- Paper 1, Paper 2 and Paper 3
Bonding is examined on Papers 1, 2 and 3.
It explains how atoms are held together in the three bond types, what that does to the structures they form, and how shape, polarity and the forces between molecules follow from it.
Sample questions from Bonding
Answer each one closed book first, then open the answer.
-
Ionic Bonding
What is the formula of the carbonate ion?
Show the answer
CO₃²⁻ -
Covalent, Dative Covalent and Metallic Bonding
In a dative covalent bond, what must the acceptor species possess?
Show the answer
An empty orbital. -
Crystal Structures: Giant Ionic Lattices and Diamond
Under what conditions do ionic compounds conduct electricity?
Show the answer
When molten or dissolved in water -
Crystal Structures: Graphite and Simple Molecular Solids
Why does graphite conduct electricity?
Show the answer
Each carbon atom uses only three electrons for bonding, leaving one electron per atom delocalised between the layers to carry charge -
Shapes of Molecules and Ions: VSEPR and Electron Pair Repulsion
What is the bond angle in a linear molecule?
Show the answer
180° -
Shapes of Molecules and Ions: Predicting Shapes and Bond Angles
What shape does a molecule with three bonding pairs and one lone pair adopt?
Show the answer
Pyramidal (trigonal pyramidal) -
Electronegativity and Bond Polarity
What do the symbols δ+ and δ- represent in a polar bond?
Show the answer
Partial positive and partial negative charges on atoms in a polar bond -
Intermolecular Forces
Which type of intermolecular force is present between all molecules?
Show the answer
Induced dipole-dipole forces (van der Waals/dispersion/London forces)
The 8 subtopics
One subtopic is one session. Work down the list.
| Subtopic | What it covers | Questions |
|---|---|---|
| Ionic Bonding | Electrostatic attraction between oppositely charged ions, and the giant lattice it produces. | 19 |
| Covalent, Dative Covalent and Metallic Bonding | Shared pairs, dative bonds where one atom supplies both electrons, and the delocalised electrons of a metal. | 23 |
| Crystal Structures: Giant Ionic Lattices and Diamond | Giant ionic lattices and giant covalent diamond, and the properties their structures explain. | 13 |
| Crystal Structures: Graphite and Simple Molecular Solids | Graphite's layers and delocalised electrons, and why simple molecular solids melt so easily. | 15 |
| Shapes of Molecules and Ions: VSEPR and Electron Pair Repulsion | Electron pair repulsion theory, and why a lone pair repels more strongly than a bonding pair. | 9 |
| Shapes of Molecules and Ions: Predicting Shapes and Bond Angles | Working out the shape and bond angle from the number of bonding and lone pairs around the central atom. | 14 |
| Electronegativity and Bond Polarity | Electronegativity trends, polar bonds, and why a molecule with polar bonds can still be non-polar. | 23 |
| Intermolecular Forces | Van der Waals, permanent dipole-dipole and hydrogen bonding, and their effect on boiling point. | 16 |
How the guide is worked
Answering a question from memory stores it far better than reading the answer again. The guide runs that as a fixed procedure on one subtopic at a time, about twenty minutes a session.
-
Step 1 · Closed book
Cover the answers. Work through one subtopic and write down what you can. Leave blanks where you have nothing.
-
Step 2 · Open book
Go back to the top. Read each printed answer and write it out in full, including the ones you had right.
-
Step 3 · Closed book again
Same questions, same order, from memory. The gap between pass one and pass three is the session result.
Read the full method, the return schedule and the research behind it.
