Question

C2H2,C2H4,C2H6 ,CH4,C3H6,C4H10,C5H8,C3H8 which of these belong to same homologous series

Answer 1

Answer:

Here CH4,C2H6,C3H8,C4H10 belongs to same homologous series I.e,Alkane

Explanation:

Because homologous series has same functional group but different no. of carbon atom.

Answer 2

Among the given compounds, $CH_4, C_2H_6, C_3H_8 and C_4H_10$ belongs to the same homologous series.

Explanation:

• The compounds which have the same general formula, they are called compounds belonging to the same homologous series.
• Among the given list of compounds, the following compounds have the same general formula which is $C_nH_{2n+2}$.

1. $C_nH_{2n+2}$ : $C_1H_{2(1)+2}$ = $CH_4$
2. $C_nH_{2n+2}$ : $C_2H_{2(2)+2} = C_2H_{4+2} = C_2H_6$
3. $C_nH_{2n+2}:$$C_3H_{2(3)+2} = C_3H_{6+2} = C_3H_8$
4. $C_nH_{2n+2} = C_4H_{2(4)+2} = C_4H_{8+2} = C_4H_{10}$

• The above given compounds are homologous series of alkanes as they posses same general formula.
