Key Formulas of JEE Main Chemistry

Formulas are central to solving numerical problems in Chemistry. Using these chemistry short notes 2026 effectively means understanding and applying key formulas.

Physical Chemistry Formulas

  • Mole Concept:

    • Moles
      n = \frac{\text{Given mass}}{\text{Molar mass}}

    • Molarity (M)
      \text{Molarity (M)} = \frac{\text{Moles of solute}}{\text{Volume of solution in L}}

    • Normality (N)
      \text{Normality (N)} = \frac{\text{Gram equivalent of solute}}{\text{Volume of solution in L}}

  • Atomic Structure:

    • Electron Energy
      E_n = -\frac{13.6 \, \text{eV}}{n^2}

    • Wavelength
      \lambda = \frac{hc}{E}

    • Bohr's Radius
      r_n = 0.529 \, \text{Å} \times n^2

  • Thermodynamics:

    • First Law: ΔU = q + w

    • Enthalpy: H = U + PV

    • Gibbs Free Energy: ΔG = ΔH - T ΔS

  • Equilibrium:

    • Equilibrium Constant
      K_c = \frac{[C]^c [D]^d}{[A]^a [B]^b} (for aA + bB ⇌ cC + dD)

    • Relation
      K_p = K_c(RT)^{\Delta n}

Inorganic Chemistry Formulas

  • Periodic Properties:

    • Effective Nuclear Charge: Z_eff = Z - S

  • Bond Order:

    • Bond Order
      \text{Bond Order} = \frac{(\text{Number of bonding electrons} - \text{Number of antibonding electrons})}{2}

Organic Chemistry Formulas

  • Hydrocarbons:

    • Alkanes:
      C_nH_{2n+2}

    • Alkenes:
      C_nH_{2n}

    • Alkynes:
      C_nH_{2n-2}

  • Degree of Unsaturation:

    • Degree of Unsaturation
      \text{Degree of Unsaturation} = \frac{2C + 2 - H + N - X}{2}
