Functional Group: Hydroxyl group ( -OH ). General Formula: C n H 2n+1 OH . Molecular Shape: The bonding around the oxygen atom is bent (V-shaped), similar to water. Example: Ethanol (C 2 H 5 OH) H H | | H - C - C - O - H | | H H Physical Properties As the carbon chain length increases (Methanol → Butanol): Boiling Point: Increases. Solubility in Water: Decreases (Methanol is very soluble; Butanol is only slightly soluble). Volatility: Decreases (they evaporate les...

Alkanes Definition: Alkanes are a homologous series of hydrocarbons that contain only carbon-carbon single covalent bonds . Because they contain only single bonds, they are known as Saturated Hydrocarbons . Each carbon atom is bonded to the maximum number of atoms (four). C H H H H ...

Other note source 📊 Introduction to Probability - Complete Theory & Formulas What is Probability? Probability measures how likely an event is to happen. It is always a number between 0 and 1, where 0 = impossible and 1 = certain. 🔑 Key Terms (Essential Vocabulary) Experiment: An action with an uncertain outcome (e.g., tossing a coin, rolling a die) Outcome: One possible result of an experiment (e.g., "Head" or "4") Event: A set of outcomes (e.g., "getting an even number") Sample Space: The complete list of all possible outcomes, written as {1,2,3,4,5,6} Favourable Outcomes: Outcomes that match the event you want Frequency: How many times an outcome appears in trials Probability Scale (0 to 1) 0 0.5 1 Impossible Even Chance Certain 📚 Section 8.1: Basic Probability (Experimental) Experimental Probability...
