Question #ee484

Answer 1

I think you mean `"homologous series"`.........

Explanation:

A late answer, but I think you mean an `"homologous series"`.........a series of (typically) organic compounds with the same general formula. And one such series is the `"alkanes"`, which has general formula `C_nH_(2n+2)`, `(n=1,2,3,....)`

And another such series is the `"alkenes"`, which has general formula `C_nH_(2n)`, `(n=1,2,3,....)`.

Such classifications are useful in organic chemistry, because we can define the reaction chemistry of a broad class of organic species, whose formulae conform to the given formula.
