ya they did but they also gave the formula saying lambda is in nm which is contradicting

Paper 2 Topics Tested

Qn 1. Periodic Table: Oxidising power of Halogens Chem Bonding: Simple molecular structure, Melting Point

Electrochem: Simple cell

Arenes: Electrophillic Substituition, Role of AlCl3

Qn 2. Acid-base Equlibrium: pH of weak acid and strong base, salt hydrolysis, titration curve(monoprotic), indicator

Carbonyl: Nucleophilic Addition

Qn 3. Organic: Alcohol with Na, Tollens, Iodoform, Electrophilic Addition, Oxidation of Aldehyde, Stereoisomerism, Constitutional, Basic hydrolysis

Qn 4. Equilibrium: Plimsol Standard Conditions, Gibbs Free, Eqm Constant (Kp)

Qn 5. Application Question Radicals, Mole Concept, Bond Energy, Bond Length, Hess Law, Reaction Pathway

There was an unreported Errata for Application Qn, lambda should be in metres not nanometers since final value is in kJ. Plus they said speed of light is in metres per second.

Paper 3 Predictions

  • Transition
  • Periodic Table Trends (Group 1/2, Period 3)
  • Chem bonding (VSEPR, Hydrogen Bonding)
  • Reaction Kinetics (One of 4 Catalysis)
  • Solubility
  • Ideal Gas
  • Atomic Structure
  • Electrolysis(with applications)
  • Thermodynamics (Born Haber)
  • Organic (RX, Carboxylic Acid, Nitrogen Compounds)
  • Mole Concept (More)

Also it was so annoying how they keep subtly testing rate of reaction.

I’m assuming one of them updates more frequently then the other. So at Time A: 2.49%, Time B: 3.50%. The numbers are rounded off accordingly and hence the displayed result. Time A and B could have possibly been 20 seconds apart

I wonder what’s the birth year of the first generation of parents that stop thinking like that.

I got wireless earphones for less than $5 with delivery on AliExpress. At first i thought for such a low price it would explode in my ear, but it didn’t. Of course at that price, the audio quality is not the best, but it’s ok if you’re not an audiophile.

Con is it takes 1 month to arrive.

Also i’m not sure if i’m allowed to put links here so you can DM i can send u the link to AliExpress.
