How Organic Chemistry is asked
General Organic Chemistry is the chapter that determines how the rest of Organic behaves for you. It supplies relatively few questions directly, but stability ordering, electronic effects and mechanism selection underlie every named reaction - which is why students who skip it find the reaction chapters look like pure memorisation.
Cheat sheet
Organic Chemistry formulas worth memorising
| Quantity | Formula |
|---|---|
| Carbocation stability | benzylic ≈ allylic > 3° > 2° > 1° > methyl |
| Carbanion stability | methyl > 1° > 2° > 3° (reverse of carbocations) |
| Acidity of alcohols | water > 1° > 2° > 3° alcohol |
| SN2 rate | rate = k[substrate][nucleophile] (second order) |
| SN1 rate | rate = k[substrate] (first order) |
| Hückel's rule (aromaticity) | cyclic, planar, conjugated, 4n + 2 π electrons |

Common mistakes in Organic Chemistry
- Applying carbocation stability order to carbanions. The orders are opposite: alkyl groups donate electrons, which stabilises a positive centre and destabilises a negative one.
- Predicting SN1 versus SN2 from the substrate alone. Solvent and nucleophile matter too - polar protic solvents and weak nucleophiles favour SN1, polar aprotic solvents and strong nucleophiles favour SN2.
- Forgetting that SN2 inverts configuration. The nucleophile attacks from the opposite face, so a chiral centre is inverted, while SN1 goes through a planar carbocation and gives a racemic mixture.
- Ranking acidity by structure alone instead of by conjugate base stability. The stronger acid is the one whose conjugate base is better stabilised by resonance, induction or electronegativity - which is why carboxylic acids beat alcohols.
- Confusing resonance with tautomerism. Resonance structures differ only in electron placement, whereas tautomers are distinct compounds in equilibrium with an atom actually moved.

JEE Organic Chemistry Quiz - FAQs
What is the fastest way to improve at Organic Chemistry for JEE?
Stop memorising reactions and start predicting intermediates. Almost every reaction reduces to which intermediate is most stable and where an electrophile or nucleophile attacks. Once those two habits are automatic, unfamiliar reactions become solvable rather than recalled.
How do I decide between SN1, SN2, E1 and E2?
Look at four things: substrate class, nucleophile or base strength, solvent and temperature. Tertiary substrates with weak nucleophiles favour SN1 and E1; primary substrates with strong nucleophiles favour SN2; strong bulky bases and higher temperatures push toward elimination.
