The image illustrates isomerism, a key concept in organic chemistry.
Isomers are compounds that have the same molecular formula but different structural formulas, meaning their atoms are arranged differently. Both butane and 2-methyl propane have the molecular formula C4H10. Butane is a straight-chain alkane, while 2-methyl propane is a branched-chain alkane. This difference in atomic arrangement gives them distinct physical and chemical properties.
