. What are isomers? Draw the structure of two isomers of butane


C4H10 Why can’t we have isomers of first three numbers of alkane series?

Best Answer

Ans. The organic compounds having the same molecular formula but different structure are known as isomers.

Isomers of butane C4H10

WERE

Isomerism is not possible in first three members of alkane series (i.e., methane, ethane, propane) because they contain only one, two or three carbons atoms respectively and with only 1,2 or 3 carbon atoms, it is not possible to have different  arrangements of carbon atoms
