Question

Write the chemical formula of two consecutive members of homologous series and state the part of this compound that determine their physical property and chemical property

Answer 1

C2H5OH. ,. C2H5OH
are two consecutive member of homologous series
part of compound that determines C.P and P.P is OH (alcohol)

Answer 2

The physical property of any particular member of a homologous series depends on its size, or its position within the homologous series. The physical properties, such as solubility, melting point, boiling point, specific gravity etc. show a gradual change with the increase in their relative molecular masses.
