Isomers28
For example, replacing one of the 12 hydrogen atoms -H by a hydroxyl group -OH on the n-pentane parent molecule can give any of three different position isomers: Functional isomers are structural isomers which have different functional groups, resulting in significantly different chemical and physical properties. (wikipedia.org)
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. (jove.com)
Spatial isomers are different because they have different spatial symmetries of molecules. (askanydifference.com)
In constitutional isomers, molecules' properties are different from each other. (askanydifference.com)
Different types of constitutional or structural isomers exist, like functional groups, positions, and skeletal. (askanydifference.com)
Isomers are the molecules that have identical molecular mass, molecular formulas, and the same number of atoms in the polyatomic set- up. (myassignment-services.com)

Chiral molecules related to each other as mutual mirror images may be separated into two enantiomers ( reflection isomers , mirror images ) with identical chemical (stability and reactivity in achiral environments) and physical (scalar) properties (melting and boiling point, spectroscopic data, etc.), except for their specific optical rotation (the optical activity of enantiomers is of equal absolute magnitude, but of opposite sign). (tu-darmstadt.de)
In chemistry, such molecules or compounds are known as isomers. (studiousguy.com)
This section describes the phenomenon of chirality of molecules in relation to their symmetry properties. (tu-darmstadt.de)
Below examples are given, in which chirality results from conformational effects, whereas chemical formulas at first sight suggest planar conformations of molecules (see 'Helical Chirality' below). (tu-darmstadt.de)
The ultimate criterion for chirality ( handedness ) of a molecule is the non-superimposability of a structure with its mirror image geometry through pure translation and/or rotation only. (tu-darmstadt.de)
Chirality of molecules may originate from configurational or conformational effects of structures. (tu-darmstadt.de)
Compounds4

A simple, but not always accurate test whether a molecule is achiral or not is the presence of a mirror plane (equal to a plane of reflection or plane of symmetry , symmetry element s ) in the structure of a molecule. (tu-darmstadt.de)
Most accurately, all molecules which have a n -fold alternating axis of symmetry (equal to an improper rotation axis or a rotary-reflection axis , symmetry element S n ) are achiral (and thus superimposable with their mirror images). (tu-darmstadt.de)
neither operation alone (rotation or reflection) is a valid symmetry operation for these molecules, but only the combination of both. (tu-darmstadt.de)
In all cases, the actually prevailing geometry (very often, but not necessarily the low-energy conformation) of a molecule must be considered when establishing the symmetry of a molecule. (tu-darmstadt.de)
The molecule pictured above is called 2-propanol can we can find one internal plane of symmetry. (pharmacology2000.com)
