Coordination Compounds
What's happening? In an octahedral field, d orbitals split into t2g (lower) and eg (higher). Delta-o = 10 Dq. Strong field ligands = large splitting = low spin complexes!
Why this matters for JEE

Crystal Field Theory is a most-searched and high-weightage topic in JEE Chemistry.

This concept appears in 1-2 questions every year. Understanding it visually builds the intuition needed to solve numerical problems fast.

JEE Application

This is one of the most-tested concepts in JEE. Master the formula and the visual intuition together.

Step-by-step

How to approach Crystal Field Theory problems

  1. Identify the variables — list what's given and what's asked.
  2. Apply the core formula — Δo = 10 Dq.
  3. Check units — convert to SI units before calculating.
  4. Verify with intuition — does the answer make chemical sense?
FAQs

Crystal Field Theory Questions

How does this concept appear in JEE?

Expect 1-2 questions per paper. Focus on understanding the relationship between variables visually.

What's the most common mistake?

Using wrong units or forgetting to convert. Always check your units first.
