NEET Chemistry: stop wasting time on Organic when Inorganic is free marks

Here's a stat that should make you uncomfortable. The average NEET aspirant spends 60% of their Chemistry prep time on Organic. 25% on Physical. 15% on Inorganic.

That allocation is exactly backwards. NEET Chemistry is roughly equal across the three — 30-35% each. So if you're spending 60% on one section, you're over-investing. And the section you're neglecting (Inorganic) is the easiest marks in the paper.

Let me explain why. And then fix your schedule.

Why Inorganic Is The Free Marks Section

Inorganic Chemistry in NEET is 85-90% NCERT-direct. Direct lines. Direct questions. "Which of the following is the most acidic oxide?" Answer is in NCERT, page 178, paragraph 2.

No derivation. No mechanism. No twist. Just recall.

Look at NEET 2024. Of the 50 Chemistry questions, roughly 16 were Inorganic. Of those, 13 were NCERT-direct. Three required minor application. Zero required derivation.

Compare with Organic. 17 questions. Of those, 8 required mechanism understanding (SN1 vs SN2, electrophilic substitution). 6 required structural analysis (identify the compound from reactions). 3 were NCERT-direct (named reactions, biomolecules).

So Organic requires deeper conceptual work for fewer guaranteed marks. Inorganic gives you marks for memorising NCERT. Same effort, much higher ROI on Inorganic.

The Inorganic Syllabus — And What Actually Matters

Not all Inorganic is equal. Here's the breakdown.

Periodic Table & Periodicity (3-4 questions). Trends. Atomic radius. Ionisation enthalpy. Electron gain enthalpy. Electronegativity. Know the trends and exceptions (like oxygen's higher electron gain enthalpy than nitrogen — actually nitrogen is less, oxygen is more negative, except fluorine is highest). Drill the exceptions. Questions love the exceptions.

p-Block (5-7 questions). This is the big one. Group 13 to 18. Know the trends down each group. Know the anomalous behaviour of the first member (Li, Be, B, C, N, O, F). Know the oxyacids and their strengths. Know the structures of the key compounds (BF3, BCl3, AlCl3 dimer, P4, P4O10, SO2, SO3, H2S2O8, etc.).

d- and f-Block (2-3 questions). Lanthanide contraction. Variable oxidation states. KMnO4 and K2Cr2O7 chemistry in detail. Colour of compounds. Magnetic moment calculation (using √[n(n+2)] formula).

Coordination Compounds (3-4 questions). Werner theory basics. IUPAC naming. Isomerism (geometrical, optical). CFT basics — splitting in octahedral and tetrahedral. Strong field vs weak field ligands. Colour and magnetic moment.

Hydrogen and s-Block (1-2 questions). Often skipped. Don't. Hydrogen's anomalous properties. Hydrides (ionic, covalent, metallic). Water hardness. NaOH and KOH differences. Na2CO3 (Washing soda) and NaHCO3 (baking soda) — industrial prep.

Metalurgy (1-2 questions). Extraction processes. Froth flotation. Leaching. Roasting. Calcination. Ellingham diagram basics. Iron, copper, aluminium extraction.

Bio-molecules overlap (1-2 questions). Sometimes Bio-molecules (glucose, fructose, amino acids, proteins, nucleic acids, vitamins) appears under Inorganic or Organic depending on classification. Treat it as NCERT-direct recall — usually 2 questions.

Total — 16-20 questions from Inorganic. Of 50 Chemistry questions. That's 32-40% of Chemistry marks, sitting in NCERT.

How To Study Inorganic — The Right Way

Most students study Inorganic wrong. They read NCERT like a novel. Front to back. Mark things yellow. Move on. Then take a test. Forget everything.

Here's the correct method.

Step 1 — Read NCERT actively. Not passively. As you read, ask "could this be a question?" If yes, mark it. Anything that's a list, a number, a comparison, a trend — mark it. Anything that's a flow — a process, a preparation method, a reaction sequence — mark it.

Step 2 — Convert to flashcards (or Anki). Front: question. Back: answer. "Anomalous behaviour of boron vs aluminium?" "Why is N2 less reactive than P4?" "Strongest reducing group in p-block?" Five hundred cards across all of Inorganic. Sounds like a lot. It's two weeks of work. Then you review daily for 18 months.

Step 3 — Drill PYQs. Examtro's NEET Inorganic PYQ bank has roughly 6,000 questions. Filter by chapter. Take 30-question sets. Three sets per chapter. Score. Note misses. Add misses to Anki.

Step 4 — Re-read NCERT every 6 weeks. NCERT re-reads are different from first reads. You're not learning. You're catching gaps. Each re-read, you'll find a fact you'd forgotten. Add it to Anki. After three re-reads, you've caught 95% of testable facts.

Time investment — 100-120 hours total over 18 months. That includes Anki reviews. Sounds like a lot? It's 6-7 hours per month. Two hours per week. Trivial. For 60-80 marks.

Organic — Where The Time Actually Goes

I'm not saying skip Organic. Far from it. Organic is 17 questions in NEET. You need those marks too.

But Organic rewards different work. Not memorisation. Understanding.

The core of Organic is mechanisms. SN1 vs SN2 vs E1 vs E2. Electrophilic aromatic substitution (halogenation, nitration, sulphonation, Friedel-Crafts). Nucleophilic addition to carbonyls. Aldol, Cannizzaro, Perkin, Claisen. Diels-Alder. These aren't formulas to memorise. They're patterns to internalise.

Time investment — 200-250 hours. Double Inorganic. For 17 questions vs 16-20. The ROI is half. So you have to budget accordingly.

The GOC foundation. General Organic Chemistry. Inductive effect. Resonance. Hyperconjugation. Carbocation stability. Reaction intermediates. This is the bedrock. Spend 30-40 hours here. Master it. Without GOC, the rest of Organic is memorisation — fragile, slow, error-prone. With GOC, you can predict mechanisms.

Hydrocarbons — alkanes, alkenes, alkynes. Mechanisms. Markovnikov, anti-Markovnikov. Ozonolysis. 20-25 hours.

Haloalkanes & Haloarenes — SN1 vs SN2 conditions. E1 vs E2 conditions. Reactivity order. 20 hours.

Alcohols, Phenols, Ethers — preparation, reactions, acidic strength comparison. 25 hours.

Aldehydes, Ketones, Acids — the biggest chunk. Aldol, Cannizzaro, Cannizzaro, Clemmensen, Wolff-Kishner. 40-50 hours.

Amines — basicity order. Hofmann, Carbylamine, diazotisation. 15-20 hours.

Biomolecules — easy marks if you've done it. 10 hours.

Polymers, Chemistry in Everyday Life — NCERT direct. 5 hours each.

The Right Time Split

Based on the above, here's the split I recommend.

Inorganic — 35% of Chem time. This includes Anki daily review (10 min/day = 60 min/week = ~50 hours/year), NCERT re-reads, PYQ practice.

Organic — 35% of Chem time. Mechanism mastery. PYQ practice. Reaction drill.

Physical — 30% of Chem time. Mole concept. Thermo. Equilibrium. Electrochemistry. Solutions. Kinetics. Formula-heavy but with application.

Not 60/25/15. Closer to 35/35/30. Notice Inorganic gets 35%? That's because the daily Anki adds up. And because NCERT re-reads are non-trivial. And because PYQ practice on Inorganic is high-volume (you can do 30 Inorganic questions in 20 minutes; Organic questions take 2-3 minutes each).

The Order To Study — When To Do What

Class 11 — start with Physical Chemistry. Mole concept, atomic structure, equilibrium, thermo. Build the foundation. Do basic Inorganic (periodic table, s-block). Touch Organic GOC at the end of Class 11.

Class 12 first half — p-Block, d-Block, Coordination. Inorganic is heavy here. Plus Organic hydrocarbons, halo, alcohols. Build Anki decks daily.

Class 12 second half — Aldehydes, ketones, acids, amines. Plus Physical — electrochem, kinetics, solutions. Plus Inorganic revision via Anki.

Last 3 months — full revision. NCERT re-read #3. Anki review (10-15 min daily). PYQ sets per chapter. Full mocks.

Last 1 month — Inorganic heavy. Because it's pure recall. You can cram Inorganic in 2 weeks and gain 20 marks. Organic? Cramming in 2 weeks gains you nothing. So Inorganic in the last weeks, Organic throughout the year.

The Brutal Reality

Look. Organic is harder. More rewarding for top students. But the marks are the same. Four marks for an SN2 question. Four marks for a "which is the strongest reducing agent" question. Same +4.

Most NEET aspirants are not top students. Most are fighting for AIR 10,000-50,000. For those kids, Inorganic is the differentiator. Free marks. Easy marks. Marks that don't require genius, just discipline.

Don't neglect Organic. But stop giving it 60% of your time. Rebalance. Watch your Chem score jump 20-30 marks in two months.
