Vedclass · Answer

(D) homologous series is a group of organic compounds having the same functional group and similar chemical properties,where each successive member differs by a $-CH_2-$ group.The molecular mass difference between two consecutive members is $14 \ u$ (since $C=12$ and $H=1$,$CH_2 = 12 + 2(1) = 14 \ u$).Option $A$ is a general formula,but in the context of defining the characteristics of a homologous series,the difference in mass is a fundamental property.However,since the question asks for a correct statement,and $A, C,$ and $D$ are all technically correct properties of alkanes,in standard chemistry curriculum,the definition of a homologous series is primarily based on the $-CH_2-$ difference.

Which of the following statements is correct for the homologous series of alkanes?
