Read the passage and answer the question :
A homologous series is a series of organic compounds which belong to the same family (i.e. possess the same functional group) and show similar chemical properties. The members of this series are called homologous and differ from each other by the number of CH2 units in the main carbon chain.

Understanding the Homologous Series
In organic chemistry, a homologous series consists of compounds that share the same functional group and exhibit similar chemical properties. The general formula for alkanes, a type of homologous series, is CnH2n + 2.
Identifying the 2nd Member
To find the 2nd member of this series:
- General Formula: For alkanes, the formula is CnH2n + 2.
- Finding n: The first member (n=1) is Methane (CH4). For the 2nd member, we set n=2.
Calculating the Formula
- For n=2:
- Carbon (C) atoms = 2
- Hydrogen (H) atoms = 2(2) + 2 = 6
- Thus, the 2nd member is C2H6, which is Ethane.
Examining the Options
Let's look at the provided options:
- a) Methane CH4: This is the 1st member (n=1).
- b) Ethane C2H6: This is indeed the 2nd member (n=2).
- c) Ethene C2H4: This is an alkene, not an alkane (n=2 but with different properties).
- d) Ethyne C2H2: This is an alkyne, not an alkane.
Conclusion
The correct answer is option 'B' Ethane C2H6, as it is the 2nd member of the homologous series corresponding to the general formula CnH2n + 2.
