An isomer (/ ˈaɪsəmər /; from Greek ἰσομερής, isomerès; isos = "equal", méros = "part") is a molecule with the same molecular formula as another molecule, but with a different chemical structure. That is, isomers contain the same number of atoms of each element, but have different arrangements of their atoms. Isomers do not necessarily share similar properties, unless they also have the same functional groups. There are two main forms of isomerism (/ ˈaɪsəmərɪzm / or / aɪ ˈsɒmərɪzm /): structural isomerism (or constitutional isomerism) and stereoisomerism (or spatial isomerism).\n\nAnswer this question: explain why isomers have different chemical and physical properties? OK. Let's think. My stream of consciousness:

The relevant information is: That is, isomers contain the same number of atoms of each element, but have different arrangements of their atoms. The answer is contain the same number of atoms of each element , but have different arrangements of their atoms.
