Study Material
Chemistry
Chemistry is the most systematic of the sciences at this level: the periodic table explains the properties, the properties explain the bonding, and the bonding explains the reactions. Learnt in that order it needs remarkably little memorising.
Start with atomic structure and the periodic table, because everything after it is an application. Everyday and applied chemistry comes last, and it is the block that general awareness papers draw on most heavily.

Today’s current affairs, checked at the source
Every item is dated, read on the conducting body’s or ministry’s own site, and written with the question it becomes. Read today’s items, take the quiz, or download the month as a PDF.
3 topics written
Read these in order
Each topic is a complete lesson — concepts, formula tables, worked examples and practice questions with explanations.
Weighting
Where Chemistry marks actually sit
A syllabus lists topics with equal visual weight, and no paper treats them that way. The table below collects what each Chemistry lesson records about the exams that examine it, so the reading order on this page can be checked against the exams you are actually sitting.
Counts are ranges observed across cycles rather than promises. The notification for your cycle is what fixes the paper, and a topic can move.
| Topic | Examined most in | Typical volume | Lesson |
|---|---|---|---|
| Atomic Structure & Periodic Table | JEE Main / Advanced; NEET Chemistry; SSC CGL / CHSL Tier 1 | 15–20% of the chemistry paper | 24 min · 16 questions |
| Chemical Bonding & Reactions | JEE Main / Advanced; NEET Chemistry; SSC CGL / CHSL Tier 1 | 20–25% of the chemistry paper | 25 min · 16 questions |
| Organic & Everyday Chemistry | JEE Main / Advanced; NEET Chemistry; SSC CGL / CHSL Tier 1 | 25–30% of the chemistry paper | 25 min · 16 questions |
How to use the table rather than read it
Find the rows naming the exam you are preparing for, and study those first regardless of where they sit in the reading order above — the order on this page is pedagogical, built so each lesson can rest on the one before it, and it is not a priority list. Where a topic you are weak at also carries the highest volume in your paper, that row is the whole of your next fortnight.
Method
How to study chemistry
Chemistry divides into three parts that need genuinely different methods, and treating them alike is why candidates find one of the three unreasonably hard.
- Physical chemistry — solve it
- Thermodynamics, equilibrium, kinetics, electrochemistry and solutions are problem subjects. They behave like physics and respond to the same treatment: work problems, do not read them.
- Organic chemistry — understand mechanisms
- Memorising reactions produces a list that collapses under an unfamiliar substrate. Understanding why a reaction proceeds — electron movement, stability of intermediates, steric effects — lets you predict reactions you have not seen.
- Inorganic chemistry — revise it
- Periodicity, group properties, coordination compounds and metallurgy are largely factual, and they reward repeated light revision rather than problem practice. This is the part that tracks the textbook most closely in examinations like NEET.
The practical implication is a split routine: problem practice for physical chemistry, mechanism study for organic, and short frequent revision passes for inorganic. Candidates who apply one method to all three usually find inorganic tedious and organic impossible.
Questions
Chemistry — FAQs
How much chemistry do general studies papers ask?
Applied chemistry at school level: common compounds and their uses, everyday reactions, materials, fuels, fertilisers and the chemistry behind health and environment questions. The theoretical structure that dominates an entrance syllabus is largely absent, so a general studies candidate should read for applications rather than for mechanism.
What is the right order for the topics?
Atomic structure first, then chemical bonding, then organic chemistry. Bonding is unintelligible without structure, and organic chemistry is a set of consequences of bonding. Read in this order and each topic explains the next; read out of order and all three become memorisation.
Is organic chemistry worth the time for a government exam?
Only at the applied level — naming, common compounds, polymers, fuels and biologically important molecules. The reaction mechanisms that occupy an entrance syllabus are rarely examined in recruitment papers, and the past papers for your own exam will show this quickly. For entrance tests the position reverses entirely.
How should I revise chemistry facts that keep slipping?
One sheet of the specific things you have actually forgotten in practice — a formula you keep misremembering, a compound whose common name you swap, a reagent you cannot place. Built from your own errors rather than from a chapter, it stays short, and short is what makes it get revised.
Read the concept, then test it the same day
Every topic ends with practice questions, and a full mock is the fastest way to find out which ones actually stuck.
