NEET 2026 Chemistry Formula Sheet (Organic + Inorganic + Physical)
Chemistry is a very important part of getting ready for NEET 2026 because it is easier to score and takes less time than Physics and Biology. Many top students think that with the right formula sheet and smart studying, you can easily get 160 or more points in Chemistry. We designed a one-stop NEET 2026 chemistry formula sheet (Organic + Inorganic + Physical) in a simple and structured way.
We looked at NEET trends at Doctor's Institute and made a plan to help students review quickly and with confidence before the test.
Why is a Chemistry Formula Sheet Crucial for NEET 2026?
NEET chemistry questions are often straightforward, based on formulas and based on NCERT. A well-organised formula sheet helps students study faster and not make silly mistakes on the test.
Key benefits of using a NEET 2026 Chemistry Formula Sheet:
- Saves revision time during the last 30 days
- Improves accuracy in numerical questions
- Helps retain reactions and exceptions
- Builds confidence for quick problem solving
A single notebook containing all formulas is far more effective than revising from multiple books.
NEET 2026 Chemistry Exam Pattern – Quick Overview
Understanding the paper pattern helps you prioritise formulas correctly.
- Total Chemistry Questions: 50
- Questions to Attempt: 45
- Total Marks: 180
- Sections:
- Physical Chemistry – 15 to 20 questions
- Organic Chemistry – 15 to 18 questions

Most questions come directly from NCERT, especially in Organic and Inorganic Chemistry.
Physical Chemistry Formula Sheet for NEET 2026
Physical Chemistry is highly scoring if formulas are clear and practice is regular. Numerical questions are mostly direct.
Some Must-Remember Physical Chemistry Formulas
Mole Concept
- Number of moles = Given mass / Molar mass
- Molarity (M) = Moles of solute / Volume (L)
- Normality (N) = Equivalent / Volume (L)
Thermodynamics
- ΔG = ΔH – TΔS
- ΔG° = –RT ln K
- Enthalpy change: ΔH = ΣH(products) – ΣH(reactants)
Chemical Kinetics
- Rate = k[A]ⁿ
- Half-life (First order): t½ = 0.693 / k
- Arrhenius equation: k = A e^(–Ea/RT)
Electrochemistry
- E°cell = E°cathode – E°anode
- ΔG° = –nFE°
- Nernst equation: E = E° – (0.0591/n) log Q
Tip from Doctor's Institute: Practice at least 20 numericals daily using these formulas to gain speed.
Organic Chemistry Formula Sheet for NEET 2026
Organic Chemistry is based on concept clarity, reaction mechanisms, and named reactions. Memorising reactions without understanding often leads to confusion.
Important Organic Chemistry Concepts & Reactions
General Organic Chemistry (GOC)
- Inductive effect: –I and +I
- Resonance stabilises molecules
- Order of acidity: Carboxylic acid > Phenol > Alcohol
- Carbocation stability: 3° > 2° > 1°
Hydrocarbons
- Alkane general formula: CₙH₂ₙ₊₂
- Alkene: CₙH₂ₙ
- Alkyne: CₙH₂ₙ₋₂
- Markovnikov’s Rule
- Anti-Markovnikov (Peroxide effect)
Important Named Reactions
- Aldol condensation
- Cannizzaro reaction
- Wurtz reaction
- Sandmeyer reaction
- Friedel-Crafts alkylation & acylation
Biomolecules
- Glucose: C₆H₁₂O₆
- Peptide bond links amino acids
- DNA contains deoxyribose sugar
Inorganic Chemistry Formula Sheet for NEET 2026
Inorganic Chemistry is pure NCERT and mostly memory-based. Regular reading is more effective than solving extra books.
Key Inorganic Chemistry Points
Periodic Table Trends
- Atomic size increases down the group
- Ionisation energy decreases down the group
- Electronegativity decreases down the group
Chemical Bonding
- Bond order = (Bonding – Antibonding electrons) / 2
- Hybridisation:
- sp – linear
- sp² – trigonal planar
- sp³ – tetrahedral
Coordination Compounds
- Coordination number: Number of ligands
- Werner’s theory
- Magnetic moment = √n(n+2)
p-Block Elements
- NH₃ is a weak base
- H₂SO₄ is a strong acid
- Oxides of non-metals are acidic
Doctor's Institute Strategy: Read NCERT line-by-line for Inorganic Chemistry every alternate day.

FAQs on NEET 2026 Chemistry Formula Sheet
1. How important is a Chemistry formula sheet for NEET 2026?
A Chemistry formula sheet is very useful for NEET 2026 because it lets you quickly go over formulas, reactions, and ideas. It helps clear up confusion, saves time and makes Physical, Organic and Inorganic Chemistry questions more accurate.
2. Which part of Chemistry is most scoring in NEET?
People think that Physical Chemistry is the most scoring subject because it has questions that are based on formulas. Students can easily get high grades if they review their formulas and do math problems. Organic Chemistry also becomes easier to score when you have a clear understanding of the concepts.
3. Is NCERT enough for NEET Chemistry 2026?
NCERT is more than enough for NEET Chemistry 2026, especially for the parts about organic and inorganic chemistry. Most of the questions come straight from NCERT lines, tables and examples. You should only use extra books to practise.
4. How many formulas should I remember for NEET Chemistry?
There is not a set number, but students should memorise all the important equations from Physical Chemistry and the most important reactions from Organic Chemistry. A short formula sheet with 200 to 250 formulas is enough.
5. How often should I revise the Chemistry formula sheet?
In the last three months before NEET, you should go over the Chemistry formula sheet every day. Looking back at formulas and reactions often helps you remember them better, also it makes tests less scary.
6. Can I score 150+ in Chemistry using only formula sheets?
You can totally score 150+ if you actually read the textbook, get what is going on and drill yourself with practice questions regularly. Formula sheets can help you remember stuff but knowing what's behind those formulas is key.
7. Which Chemistry section has the least negative marking risk?
Inorganic Chemistry has the least negative marking risk because questions are factual and direct. If NCERT is thoroughly revised, answers become straightforward and less confusing compared to calculation-based questions.
8. Are Organic Chemistry reactions important for NEET 2026?
Organic chemistry reactions are very important for NEET 2026. People often ask about named reactions, mechanisms and conversions. Looking at reaction flowcharts often makes them more precise, which in turn gives you a confidence boost.
