Coordination Chemistry — Class 12 Chemistry (Samacheer Kalvi)
TN State Board (Samacheer Kalvi) Class 12 Chemistry, Chapter 5. IUPAC naming, isomerism, VBT and CFT.
1. About this chapter
This chapter covers Coordination Chemistry as part of the Class 12 Samacheer Kalvi Chemistry curriculum. It deals with iupac naming, isomerism, vbt and cft and builds conceptual understanding essential for the TN HSC Public Exam.
By the end of this chapter, students will be able to:
- Name coordination compounds using IUPAC rules
- Apply crystal field theory to predict colour and magnetism
2. Key concepts
- Concept 1: Name coordination compounds using IUPAC rules.
- Concept 2: Apply crystal field theory to predict colour and magnetism.
3. Important terms and formulas
| Term / Formula | Description |
|---|---|
| Name coordination compounds using… | Name coordination compounds using IUPAC rules |
| Apply crystal field theory… | Apply crystal field theory to predict colour and magnetism |
4. Worked examples
Example 1. Applying a key concept from this chapter.
Solution: Identify the relevant principle → apply the formula or rule → state the answer with correct units.
Example 2. A typical exam-style question on coordination chemistry.
Solution: Break the problem into steps, use the appropriate formula and verify the answer.
5. Common mistakes
- Mistake: Skipping units or forgetting to state them. Fix: Always write units alongside every quantity and answer.
- Mistake: Confusing similar terms or concepts in this chapter. Fix: Make a comparison table of the terms during revision.
6. Practice (exam-style)
- Define the main term or principle covered in Chapter 5.
- Give two real-life examples related to coordination chemistry.
- Solve a short numerical or descriptive question from this chapter.
- State one important formula and explain each symbol.
7. Answer key (hints)
- Refer to section 2 (Key concepts) above for the definition.
- Examples should be drawn from daily experience and local context.
- Apply the formula from section 3, show all steps clearly.
- Formula with units — refer to the textbook glossary for symbol meanings.
8. Quick revision
- Class 12 Chemistry — Chapter 5: Coordination Chemistry.
- Core idea: IUPAC naming, isomerism, VBT and CFT.
- Key outcomes: Name coordination compounds using IUPAC rules; Apply crystal field theory to predict colour and magnetism.
- Always revise diagrams / tables from the Samacheer Kalvi textbook before the exam.
