CH3OH

उत्तर
Homologous series: A series of organic compounds having similar structures and chemical properties and in which the successive compounds differ by -CH2 group is called a homologous series. A homologue of CH3OH will differ by the -CH2 group; therefore, methanol's successive homologue will be ethanol (C2H5OH).
The structural formula of ethanol is as follows:
