🧪 NEET Chemistry Master Tool

Daily questions • Smart tricks • Must-remember formulas

Question:

🔹 **pH Shortcut:** pH = 14 − pOH (at 25°C)

🔹 **Hybridization Rule:** Steric number = σ bonds + lone pairs

🔹 **Periodic Trend:** Smaller size → higher ionization energy

🔹 **Organic Tip:** More substituted carbocation = more stable

Physical Chemistry

M = moles / volume (L)

pH = −log[H⁺]

ΔG = ΔH − TΔS

Organic Chemistry

SN1 → Carbocation → Racemization

SN2 → Backside attack → Inversion

Inorganic Chemistry

F > O > N > Cl (Electronegativity)

d⁵ & d¹⁰ → Extra stability
