| 12 | Consider the bond orders of the following species:
O2+ O2− CO O2²− Which option correctly gives their bond-order values? | 1 429 |
| 13 | Which one of the following molecules has a permanent dipole moment? | 1 429 |
| 14 | ⚛️ CHEMICAL BONDING — OLYMPIAD QUICK REVISION
1. LEWIS STRUCTURE
📌 Count total valence electrons → make bonds → complete octets.
🔥 Formal Charge:
FC = V − N − B/2
⚠️ Octet exceptions:
• BF3 → incomplete octet
• NO → odd electron
• SF6 → expanded octet
2. VSEPR THEORY
Electron pairs repel and arrange to minimise repulsion.
🔥 Repulsion:
LP-LP > LP-BP > BP-BP
📌 Common shapes:
AX2 → Linear → 180°
AX3 → Trigonal planar → 120°
AX4 → Tetrahedral → 109.5°
AX3E → Trigonal pyramidal
AX2E2 → Bent
AX5 → Trigonal bipyramidal
AX6 → Octahedral
3. HYBRIDISATION
Steric Number = σ bonds + lone pairs
SN 2 → sp
SN 3 → sp²
SN 4 → sp³
SN 5 → sp³d
SN 6 → sp³d²
🔥 Multiple bond = ONE electron domain.
4. SIGMA & PI BONDS
Single → 1σ
Double → 1σ + 1π
Triple → 1σ + 2π
⭐ Every covalent bond contains ONE σ bond.
5. MOT — MOLECULAR ORBITAL THEORY
Bonding MO → Lower energy → Stabilising
Antibonding MO → Higher energy → Destabilising
🔥 Bond Order:
BO = ½(Bonding e⁻ − Antibonding e⁻)
Higher BO →
• Stronger bond
• Shorter bond
• Higher bond energy
6. MAGNETIC NATURE
Unpaired electrons → PARAMAGNETIC
All electrons paired → DIAMAGNETIC
⭐ O2:
BO = 2
2 unpaired electrons
→ PARAMAGNETIC 🔥
7. BOND PARAMETERS
Higher bond order:
↑ Bond strength
↑ Bond energy
↓ Bond length
Therefore:
C≡C > C=C > C-C
in bond strength.
8. DIPOLE MOMENT
μ = q × r
Molecular dipole moment = VECTOR SUM of bond dipoles.
⚠️ Polar bonds ≠ necessarily polar molecule.
Example:
CO2 → polar bonds but overall NON-POLAR.
⚡ OLYMPIAD MUST-REMEMBER
FC = V − N − B/2
LP-LP > LP-BP > BP-BP
SN = σ bonds + lone pairs
SN 2 → sp
SN 3 → sp²
SN 4 → sp³
SN 5 → sp³d
SN 6 → sp³d²
Single → 1σ
Double → 1σ + 1π
Triple → 1σ + 2π
BO = ½(Bonding e⁻ − Antibonding e⁻)
Higher BO → Shorter + Stronger bond
O2 → Paramagnetic
🎯 GOLDEN RULE:
LEWIS → ELECTRONS
VSEPR → SHAPE
HYBRIDISATION → ORBITALS
MOT → BOND ORDER + MAGNETISM | 1 477 |

| 19 | ⚡ ELECTRICITY — OLYMPIAD QUICK REVISION
1. ELECTRIC CURRENT
Electric current = rate of flow of electric charge.
I = Q/t
📌 SI Unit → Ampere (A)
Therefore:
Q = It
2. POTENTIAL DIFFERENCE
Potential difference = Work done per unit charge.
V = W/Q
📌 SI Unit → Volt (V)
Therefore:
W = VQ
⭐ Remember:
1 V = 1 J/C
3. OHM'S LAW
For a conductor at constant temperature:
V = IR
Therefore:
I = V/R
R = V/I
📌 SI Unit of resistance → Ohm (Ω)
4. RESISTANCE OF A WIRE
Resistance depends on:
R = ρL/A
Where:
ρ = resistivity
L = length
A = cross-sectional area
📌 SI Unit of resistivity → Ω·m
5. EFFECT OF CHANGING DIMENSIONS
If length becomes n times:
L' = nL
Then:
R' = nR
If radius becomes n times:
A' = n²A
Therefore:
R' = R/n²
A = πr²
6. SERIES COMBINATION
Resistors connected end-to-end:
R_eq = R₁ + R₂ + R₃ + ...
📌 Same current flows through every resistor.
I₁ = I₂ = I₃
Voltage divides:
V = V₁ + V₂ + V₃
For two resistors:
V₁/V₂ = R₁/R₂
7. PARALLEL COMBINATION
For parallel resistors:
1/R_eq = 1/R₁ + 1/R₂ + 1/R₃ + ...
📌 Same potential difference across every branch.
V₁ = V₂ = V₃
Current divides:
I = I₁ + I₂ + I₃
For two resistors:
R_eq = R₁R₂/(R₁ + R₂)
8. SPECIAL CASE — IDENTICAL RESISTORS
n identical resistors, each resistance R:
SERIES:
R_eq = nR
PARALLEL:
R_eq = R/n
9. ELECTRIC POWER
Power = rate of electrical energy consumption.
P = VI
Using V = IR:
P = I²R
Also:
P = V²/R
📌 SI Unit → Watt (W)
⭐ Three important forms:
P = VI
P = I²R
P = V²/R
10. ELECTRICAL ENERGY
Electrical energy:
E = Pt
Therefore:
E = VIt
Also:
E = I²Rt
and
E = V²t/R
📌 Commercial unit:
1 kWh = 3.6 × 10⁶ J
11. HEATING EFFECT OF CURRENT
According to Joule's law:
H = I²Rt
Also:
H = VIt
and
H = V²t/R
12. EMF AND INTERNAL RESISTANCE
A real cell has internal resistance "r".
If external resistance is "R":
I = E/(R + r)
Terminal voltage:
V = E − Ir
Therefore:
V = IR
for the external circuit.
📌 E = EMF of cell
📌 r = internal resistance
13. CELLS IN SERIES
For identical cells connected in series:
E_eq = nE
r_eq = nr
Current through external resistance R:
I = nE/(R + nr)
Series cells are useful when higher voltage is required.
14. CELLS IN PARALLEL
For "n" identical cells in parallel:
E_eq = E
r_eq = r/n
Current:
I = E/(R + r/n)
Parallel cells reduce effective internal resistance.
15. KIRCHHOFF'S CURRENT LAW
At any junction:
Total current entering = Total current leaving.
ΣI_in = ΣI_out
📌 Based on conservation of charge.
Junction Rule:
IN = OUT
16. KIRCHHOFF'S VOLTAGE LAW
Around any closed loop:
ΣV = 0
Or:
Sum of EMFs = Sum of potential drops
📌 Based on conservation of energy.
Loop Rule:
TOTAL RISE = TOTAL DROP
17. CIRCUIT NUMERICAL STRATEGY
For a complex circuit:
STEP 1 → Identify series and parallel sections.
STEP 2 → Find equivalent resistance.
STEP 3 → Find total current.
I = V/R_eq
STEP 4 → Find branch currents/voltages.
STEP 5 → Calculate power if required.
P = VI
OLYMPIAD MUST-REMEMBER
Current:
I = Q/t
Ohm's Law:
V = IR
Resistance:
R = ρL/A
Series:
R_eq = R₁ + R₂ + ...
→ SAME CURRENT
Parallel:
1/R_eq = 1/R₁ + 1/R₂ + ...
→ SAME VOLTAGE
Power:
P = VI = I²R = V²/R
Heat:
H = I²Rt
🔋 Cell:
I = E/(R + r)
Terminal voltage:
V = E − Ir
🔄 Kirchhoff Junction:
ΣI_in = ΣI_out
⭕ Kirchhoff Loop:
ΣV = 0
🎯 GOLDEN RULE
SERIES → SAME CURRENT
PARALLEL → SAME VOLTAGE
POWER → P = VI
HEAT → H = I²Rt
COMPLEX CIRCUIT → REDUCE → FIND CURRENT → FIND BRANCH VALUES | 1 718 |
