Variable Oxidation States of d Block Elements Part: 02 | NCERT Titanium +2, +3, +4 Class 12 JEE NEET

Описание: In this detailed Class 12 Chemistry lecture, we dive deep into the variable oxidation states of d-block elements (transition metals) with special focus on Titanium (Ti)

A high-weightage topic for JEE Main, JEE Advanced, NEET, and board exams.

What You’ll Learn:

The Ti^{2+} Mystery: Why is Titanium(II) so unstable in water? We look at the redox reaction that produces Hydrogen gas.

The Purple Power of Ti^{3+}: Understanding the [Ti(H_2O)_6]^{3+} aqua complex and the d \rightarrow d transitions that cause its iconic color.

The Stability of Ti^{4+}: Why the +4 state is the "noble gas" goal for Titanium and how it forms Titanyl ions (TiO^{2+}).


Electron Configurations: A deep dive into 3d^2, 3d^1, and 3d^0 configurations and their magnetic properties.

🔹 Why do transition metals show variable oxidation states?

🔹 Electronic configuration of d-block elements & how it leads to multiple states?

🔹 Oxidation states of Titanium: +2, +3, +4.

🔹 Why is +4 oxidation state the most stable in Titanium? (d⁰ configuration & noble gas core.)

🔹 Common compounds of Ti in different states (TiO₂, TiCl₃, TiCl₄, etc.)



Perfect for CBSE Class 12, NEET 2025/2026 Chemistry preparation, and JEE aspirants!
