Chemistry Shortcuts for JEE

1. Periodic Table Mnemonics

Example: 1st group (alkali metals) –
Hi Na Kare Ruby Sir Par Football Akela
(H, Na, K, Rb, Cs, Fr)

2. Redox Reaction Shortcut

OIL RIG: Oxidation Is Loss (of electrons), Reduction Is Gain (of electrons)

3. Organic Chemistry

• SN1 = Carbocation → rearrangement possible
• SN2 = Backside attack → inversion of configuration
• Markovnikov Rule = "Rich gets richer"

4. Thermodynamics Formulae

• ΔG = ΔH – TΔS
• Q = mcΔT
• PV = nRT (Ideal Gas Law)

5. Inorganic Chemistry Trick

Group-wise learning karo: block ke reactions aur colors important hain. NCERT ke diagrams aur reactions highlight karke yaad karo.
