Chemical Bonding(11th), every formula

22 formulas, typeset and free. Print it, or keep it open beside your practice.

Formal charge
$F C = V - L - \frac{1}{2} B$
V=valence e⁻, L=lone-pair e⁻, B=bonding e⁻
Bond order (MOT)
$B O = \frac{1}{2} (N_{b} - N_{a})$
Dipole moment
$μ = q \times d$
Dipole moment units
$1 D = 3.336 \times 1 0^{- 30} C m$
Percent ionic character
$% = \frac{μ _{o b ser v e d}}{μ _{i o ni c}} \times 100$
Fajans' rules
$covalent character ↑ with small cation, large anion, high charge$
Hybridisation (steric number)
$H = \frac{1}{2} (V + M - C + A)$
V=valence, M=monovalent, C/A=charge
sp geometry
$linear, 18 0^{\circ}$
sp² geometry
$trigonal planar, 12 0^{\circ}$
sp³ geometry
$tetrahedral, 109. 5^{\circ}$
sp³d geometry
$trigonal bipyramidal$
sp³d² geometry
$octahedral, 9 0^{\circ}$
VSEPR lone-pair effect
$lp-lp > lp-bp > bp-bp repulsion$
Bond length vs bond order
$bond length ↓ as bond order ↑$
Bond energy vs bond order
$bond energy ↑ as bond order ↑$
Magnetic character (MOT)
$unpaired e⁻ \Rightarrow paramagnetic$
Number of σ and π bonds
$single = 1 σ, double = 1 σ + 1 π, triple = 1 σ + 2 π$
Electronegativity difference
$Δ E N > 1.7 \Rightarrow ionic$
Lattice energy (Born–Landé)
$U \propto \frac{q _{+} q _{-}}{r _{+} + r _{-}}$
Hydrogen bond strength
$\approx 10 - 40 kJ/mol$
Bond order (fractional)
$B O = \frac{total bonds}{resonance structures}$
Dipole of symmetric molecule
$μ = 0$
