Question

A hydrocarbon which does not belong to the same homologous series of carbon compounds is ______.

Options

• C₄H₁₀

• C₆H₁₄

• C₇H₁₄

• C₁₀H₂₂

Answer 1

A hydrocarbon which does not belong to the same homologous series of carbon compounds is C₇H₁₄.

Explanation:

The hydrocarbon that does not belong to the same homologous series (alkanes) as the others is C₇H₁₄, which is an alkene, while the others (C₄H₁₀, C₆H₁₄, and C₁₀H₂₂) are alkanes.

Here's a breakdown:

• Alkanes: Alkanes are saturated hydrocarbons with the general formula C_nH_2n+2.
• Alkenes: Alkenes are unsaturated hydrocarbons with the general formula C_nH_2n.

Let's analyze each option:

• C₄H₁₀: n = 4, 2n + 2 = 10. This fits the alkane formula (C_nH_2n+2).
• C₆H₁₄: n = 6, 2n + 2 = 14. This also fits the alkane formula (C_nH_2n+2).
• C₇H₁₄: n = 7, 2n = 14. This fits the alkene formula (C_nH_2n).
• C₁₀H₂₂: n = 10, 2n + 2 = 22. This fits the alkane formula (C_nH_2n+2).
