What is meant by isomers ? "We cannot have isomers of first three members of alkane series’’.Give reason to justify this statement. Draw the structures of two isomers of pentane.
(i) The compounds with identical molecular formula but different structures are called isomers or more accurately structural isomers.
(it) Because there is no branching possible for first three members, i.e., carbon atoms remain linked in one chain only and there is no possibility of formation of side chain.
