Question

What are isomers? “Isomers of the first three members of alkane series are not

possible”. Give reason to justify this statement and draw structures of two isomers of

butane, C4 H10

Answer 1

Isomers are the compounds having same chemical formula but different structures.

Isomers of methane, ethane and propane is not possible because even if we will try to change the place of carbon the structure remains the same.

Answer 2

HEY FRND.

ISOMERS HAVE THE SAME NUMBER OF ATOMS BUT DIFFERENT ARRANGEMENTS.

THE ISOMERS OF THE FIRST THREE MEMBER OF ALKANE SERIES ARE NOT POSSIBLE BECAUSE THEY CAN'T BE BRANCHED.

FOR BRANCHING , AT LEAST 4 CARBON ARE REQUIRED.
