Monobromrophenols have three isomers because there is only one bromine atom that can occupy one of three ring positions on the phenol molecule; 2-bromophenol, for example, is the isomer that has a bromine atom in the ortho position.

Isomers themselves exist in many varieties but can generally be classified as structural isomers or stereoisomers. Structural isomers have a different ordering of bonds and/or different bond connectivity from one another, as in the case of hexane and its four other isomeric forms ( 2-methylpentane , 3-methylpentane , 2,2-dimethylbutane , and 2 ...
Atropisomers are conformational isomers which can be separated due to restricted rotation. [18] The equilibrium between conformational isomers can be observed using a variety of spectroscopic techniques. [19] Protein folding also generates conformers which can be observed.
In some cases, making drugs from atropisomers is challenging because isomers may interconvert faster than expected. Atropisomers also might interact differently in the body, and as with other types of stereoisomers , it is important to examine these properties before administering drugs to patients.
Isotopomers or isotopic isomers are isomers which differ by isotopic substitution, and which have the same number of atoms of each isotope but in a different arrangement. For example, CH 3 OD and CH 2 DOH are two isotopomers of monodeuterated methanol .
