1.	Why members of homologous series show different physical properties where as they have same chemical properties?
Answer» ANSWER:-- Homologous Series:- ◆ It is Series of compounds in which in the same functional groups substitute for hydrogen in a carbon chain. ◆ For instance, the Alcohols: CH2OH C2H5OH C3H7OH C4H9OH ◆ The SUCCESSIVE MEMBER differs by one -CH2 UNIT and 14 unit of mass. ◆ The chemical properties are imparted by the functional groups thus all member have similar properties. But the members have different physical properties. ◆ The physical properties vary among the members of Homologous Series due to different in their molecular mass. ◆ Melting point and boiling point will increase with increasing molecular mass.
