Model Answer
(C) C₇H₁₄
C₄H₁₀, C₆H₁₄, and C₁₀H₂₂ follow the alkane general formula CₙH₂ₙ₊₂, while C₇H₁₄ follows CₙH₂ₙ (alkene series), so it does not belong to the same homologous series.

Explanation
- Alkanes follow CₙH₂ₙ₊₂: C₄H₁₀ (n=4: 2×4+2=10✓), C₆H₁₄ (n=6: 14✓), C₁₀H₂₂ (n=10: 22✓) — all alkanes.
- C₇H₁₄ fits CₙH₂ₙ (n=7: 2×7=14✓) — this is the alkene series, a different homologous series.
- In MCQs like this, quickly apply the general formula to each option to identify the odd one out.
