Vedclass · Answer

(A) homologous series is a group of organic compounds having the same functional group and similar chemical properties,where each successive member differs by a $-CH_2$ (methylene) group.Since the atomic mass of $C$ is $12$ and $H$ is $1$,the molar mass of a $-CH_2$ group is $12 + (2 	imes 1) = 14 \ g/mol$.Therefore,the numerical difference in the molar masses of any two successive members (such as the second and third members) is $14$.
