Question

define functional group and homologous series.

Answer 1

Functional group - an atom or group of atom present in molecule which largely determine its chemical properties is called functional group.

Homologous series- The series in which carbon compounds are differs by CH2 unit is called homologous series.

Answer 2

Functional Groups -: A functional group is an atom of a group of atoms which determines the characteristic properties of a particular compound.

Homologous series-: A homologous series is defined as a series of organic compounds having similar functional group and similar properties, in which the successive members or compounds differ by CH2 group...
