Isomers are compounds having the same chemical formula but having different arrangements of atoms. There are many types of isomers that are defined based on the way in which the atomic arrangements differ. Structural isomerism is a form of isomerism in...

The term isomer (meaning same member) refers to two molecules that have the same chemical formula, but which differ according to the spacial arrangement of their atoms. Molecules that are isomers have the same number and kind of atoms, but they differ...

Just as early chemists were beginning to understand the nature of chemical compounds, a new twist complicated the picture. They found that the molecular formula for two different compounds can be the same. Because the atoms are connected in different...

(from Greek, isos: equal, meros: part) Certain chemicals can exist in two different forms, called isomers. This property arises when there is an asymmetry in the structure of a MOLECULE. Because of this asymmetry, any other components of the molecule...

One of two or more substances with identical molecular formulas but different configurations, differing only in the arrangement of their component atoms. It usually refers to stereoisomers (rather than constitutional isomers or tautomers; &see;...

One of two or more substances whose molecules possess the same atoms (i.e. they have the same molecular weight) but these arranged in a different structure – the isomers consequently have at least one difference in their physical or chemical...

More than one organic compound can exist with the same empirical formula. Structural formulae will...

In chemistry, isomers are molecules with the same chemical formula and often with the same kinds of chemical bonds between atoms, but in which the atoms are arranged differently (analogous to a chemical anagram). Many isomers share similar if not...
