A homologous series is a series of organic compounds which belong to the same family (i.e. possess 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. Which of the following represent the name and formula of the 2nd member of homologous series having general formula `C_nH_(2n+2)`?

Options

A. Methane
B. Ethane
C. Ethyne
D. Ethene

Answer

B

Explanation

`C_nH_(2n+2)` formula corresponds to alkane series and if we are considering second member that means n= 2 thus it will be `C_2H_6` which is ethane
