Correct Answer: C 2 H 6 and C 3 H 9


Solution : The correct answer is C 2 H 6 and C 3 H 9 .

A homologous series is a collection of compounds that share some functional groups but differ from one member to the next by CH 2 . Organic molecules with the same general formula have been found to contain carbon chains of different lengths. C 3 H 9 is not a valid hydrocarbon since it implies an unsaturation or extra hydrogen atoms.
