Answer 1

 1 all the members of the series can be represented by same general formula

2 all the compounds of series show similar chemical properties

3 the difference in the molecular masses of any 2 homologues is 14u

4 any 2 adjacent homologues differ by 1 carbon atom and 2 hydrogen atom intheir formula

Answer 2

1) The various members of homologous series have the same general method of preparation.for example all alkanes can be prepared by the reduction of alkyl halide.

2) The various members of homologous series show regular graduations in physical properties and have same chemical properties.
