Class 12 Chemistry is very important for CBSE board exams, JEE, NEET, and other entrance tests. Many students find chemistry difficult because of chemical reactions, formulas, and theories. But don’t worry!
This guide will help you understand Chemistry in an easy way. Here, you will find:
✅ Chapter-wise notes to help you understand every topic
✅ Handwritten-style notes for better memory
✅ Important questions & answers for board exams
✅ Quick revision notes to save time
With these simple and clear notes, you can study faster, understand better, and score higher in exams.
The NCERT Chemistry book is divided into two parts:
1️⃣ Physical & Inorganic Chemistry – Covers topics like Solid State, Solutions, Electrochemistry, and Periodic Elements.
2️⃣ Organic Chemistry – Focuses on Haloalkanes, Alcohols, Phenols, and Biomolecules.
Below are chapter-wise notes with summaries, important topics, and exam questions.
? What You Will Learn:
✔️ Difference between Crystalline & Amorphous solids
✔️ Unit cell, packing efficiency, and crystal lattices
✔️ Electrical & magnetic properties of solids
? Important Q&A:
❓ What is the difference between crystalline and amorphous solids?
✅ Crystalline solids have a fixed shape & structure, while amorphous solids don’t have a regular arrangement.
? What You Will Learn:
✔️ Different types of solutions and solubility
✔️ Colligative properties (boiling point, freezing point)
✔️ Raoult’s Law and Henry’s Law
? Important Q&A:
❓ What is Raoult’s Law?
✅ It says that adding a solute to a solvent lowers its vapor pressure.
? What You Will Learn:
✔️ Galvanic & Electrolytic cells
✔️ Batteries & fuel cells
✔️ Nernst equation and its applications
? Important Q&A:
❓ Why is a salt bridge needed in a galvanic cell?
✅ It keeps the charges balanced so that the cell can continue working.
? What You Will Learn:
✔️ Reaction rates and rate laws
✔️ Factors that affect reaction speed (temperature, pressure, catalyst)
✔️ Activation energy and Arrhenius equation
? Important Q&A:
❓ How does temperature affect the rate of a reaction?
✅ When temperature increases, molecules move faster, causing more collisions and speeding up the reaction.
? What You Will Learn:
✔️ Properties & reactions of haloalkanes (alkyl halides) & haloarenes (aryl halides)
✔️ SN1 and SN2 reactions (types of nucleophilic substitution)
✔️ Harmful effects of CFCs on the ozone layer
? Important Q&A:
❓ Why are SN2 reactions faster in primary alkyl halides?
✅ Less crowding around the carbon makes it easier for the nucleophile to attack.
? What You Will Learn:
✔️ Preparation and properties of alcohols, phenols, and ethers
✔️ Why phenols are more acidic than alcohols
✔️ Important reactions of alcohols and phenols
? Important Q&A:
❓ Why is phenol more acidic than alcohol?
✅ Phenoxide ions are stable due to resonance, so phenol easily loses an H⁺ ion.
✔️ Simple & Easy to Understand – No complicated words, just clear explanations.
✔️ Short & to the Point – Saves time while covering all key topics.
