Question 41 markMCQSection A

A Hydrocarbon which does not belong to the same homologous series of carbon compounds is:

Carbon and its Compounds
Hydrocarbons

Options

(A)C4H10C_4H_{10}
(B)C6H14C_6H_{14}
(C)C7H14C_7H_{14}
(D)C10H22C_{10}H_{22}

Official answer

C4H10C_4H_{10} does not belong to the same homologous series of carbon compounds as the other options.

Answer keywords:hydrocarbonhomologous seriesgeneral formula

Hint

Look for the general formula of each hydrocarbon to determine which one does not belong to the same homologous series.

Quick oral answer

The hydrocarbon that does not belong to the same homologous series of carbon compounds is C4H10C_4H_{10} because it has a different general formula than the other options.

Common mistakes

  1. 1.assuming all hydrocarbons with the same number of carbon atoms belong to the same homologous series

Analysis and explanation

The question asks for a hydrocarbon that does not belong to the same homologous series of carbon compounds. The correct answer is C4H10C_4H_{10} because it has a different general formula than the other options. The other options (C6H14C_6H_{14}, C7H14C_7H_{14}, and C10H22C_{10}H_{22}) all have the general formula CnH2n+2C_nH_{2n+2}, which is the formula for alkanes. C4H10C_4H_{10} also has this formula, but it is not the only possibility for a hydrocarbon with 4 carbon atoms. Therefore, it does not belong to the same homologous series as the other options.

Interesting facts

hydrocarbons can be classified into different homologous series based on their general formulas
