Question

what are homologous series of carbon compounds?wrie two consecutive member of homogeneous is ries of aldehyde? state which part of them tell. (1) physical property (2) chemical property

Answer 1

A homologous series may be defined as a family of organic compounds having the same functional group,and the successive(adjacent) members of which differ by a CH _{2} unit or 14 mass units.

Two consecutive members of homologous series of Aldehydes: CH _{3} CHO and C _{2} H _{5} CHO.

A carbon compound is made up of two parts: R-F,where R is the hydrocarbon part and F is the functional group part.
So,this R (hydrocarbon) part determines the physical properties of a compound and the F (functional group) part determines the

Answer 2

The series in which functional group and chemical properties remains same but the difference between the two members is CH²is called homologous series of carbon compounds.
Two member of aldehyde is
1)Ethanal and
2) propanal.
Physical properties changes but
Chemical properties remains same
