Question

CH4 ,C2H6 ,C3H8 ,C4H10 ....... ARE CALLED HOMOLOGOUS SERIES. WHY?

Answer 1

Answer:CH4 ,C2H6 ,C3H8 ,C4H10 ....... ARE CALLED HOMOLOGOUS SERIES because homologous series are the series in which there is difference of CH2 in between previous and next v

Explanation:

Answer 2

Because they differ by $CH_2$ repeating unit.

Explanation:

A homologous series is a series of compounds with the same functional group and similar chemical properties in which the members of the series differ by the number of repeating units they contain.

The functional group which represents alkanes has suffix ane.. Thus the five compounds of alkanes which differ by a $CH_2$ unit are $CH_4$ , $C_2H_6$ , $C_3H_8$ and $C_4H_{10}$ are named as methane, ethane, propane and butane containing 1, 2 , 3 and 4 carbon atoms respectively.
