Q1: What are homologous series? Give characteristics and an example.
Homologous Series: A series of organic compounds with:
1. Same general formula
2. Successive members differing by one CH2 unit
3. Similar chemical properties
4. Gradual change in physical properties
5. Prepared by similar methods
Characteristics:
1. Differ by CH2 (mass difference = 14 amu)
2. Each ...
Q2: Draw and name the structural isomers of C4H10 (butane)
Structural isomers of C4H10 have same molecular formula but different structural arrangements:
Isomer 1: n-Butane (Butane)
Structure: CH3-CH2-CH2-CH3
Straight chain of 4 carbons
Boiling point: -0.5°C
Isomer 2: 2-Methylpropane (Isobutane)
Structure: CH3

Q3: What is covalent bond? Explain sigma (σ) and pi (π) bonds with examples.
Covalent Bond: Chemical bond formed by sharing of electrons between two atoms.
Sigma (σ) Bond:
- Strongest type of covalent bond
- Head-on overlap of atomic orbitals (or orbital lobes)
- Electron density concentrated along the internuclear axis
- Free rotation possible around σ bond
- All single bo...
