उत्तर
C4 H8
Explanation -
The succeeding members of the homologues series differ by a —CH2 - unit. The general formula for the alkane is CnH2n+2. Methane (CH4), ethane (C2H6) and propane (C3H8) are members of homologues series for alkanes while butene (C4H8) is the fourth member of homologues series for alkene.
