What is Chemistry? Branches of Chemistry Part 2 — Class 9 Chemistry Lecture Summary
Lecture Overview
Continuing from the previous video, this lecture covers the remaining Branches of Chemistry. The teacher explains how chemistry branches out into specialized fields like Inorganic, Biochemistry, Industrial, Nuclear, Environmental, and Analytical Chemistry.
Main Concepts Explained by the Teacher
The teacher contrasts Inorganic Chemistry (studying non-carbon elements) with Organic Chemistry. He then explains Biochemistry as the chemistry of living organisms. The lecture also touches on Industrial Chemistry (mass production of chemicals), Nuclear Chemistry (radioactivity), Environmental Chemistry (pollution), and Analytical Chemistry (separating and identifying components of a sample).
Important Definitions and Terms
- Inorganic Chemistry: The study of all elements and their compounds, except hydrocarbons.
- Biochemistry: The study of the structure, composition, and chemical reactions occurring in living organisms.
- Analytical Chemistry: The branch dealing with the separation and analysis of a sample to identify its components.
Key Points and Lists from the Lecture
- Biochemistry deals with metabolism, digestion, and DNA.
- Industrial chemistry includes manufacturing glass, cement, and fertilizers.
- Analytical chemistry involves qualitative (what is it?) and quantitative (how much is it?) analysis.
What Students Should Remember
Look, you must be able to link practical examples to the correct branch. If an exam asks about the manufacturing of fertilizers, you should instantly know it belongs to Industrial Chemistry. If it asks about testing water quality, that's Environmental and Analytical Chemistry.

Final Recap & Board Exam Notes
This class wraps up the scope of chemistry. By understanding these diverse branches, 9th class students realize that chemistry is not just one subject, but a collection of interconnected fields that govern everything from factories to human DNA.
- This is a total lifesaver for 9th class Punjab Board and FBISE exams.*
Make sure to review this before your BISE Lahore or Federal board finals. It helped me a lot.
