🧪 Key Concepts Explained (With Examples)

🔹 Carbon

Carbon is a versatile element that forms a large number of compounds.

📌 Example: Methane (CH₄)

🔹 Covalent Bonding

Sharing of electrons between atoms.

📌 Example: CH₄

👉 Carbon shares electrons instead of losing/gaining

🔹 Hydrocarbons

Compounds made of carbon and hydrogen.

📌 Example: Ethane (C₂H₆)

🔹 Functional Groups

Groups that determine properties of compounds.

📌 Example:

Alcohol → –OH
Carboxylic acid → –COOH

🔹 Homologous Series

Group of compounds with same functional group and similar properties.

👉 Homologous series show gradual change in properties
