Stereoisomers are isomeric compounds with the same molecular formula and also have the same connectivity of atoms, but only differ in the 3 dimensional arrangements of atoms in space, hence also known as spatial isomers. Conformational isomers are those isomers in which the relative positions of some of the atoms differ in the molecule in the three-dimensional space due to rotation about sigma bonds. Conformational Isomers. Types of conformational isomers Representation of conformational isomers diagrammatically How conformational isomerism has implications on stability, reactivity and molecular behaviour in reactions Geometrical or cis-trans isomerism and properties of geometrical isomerism. The reason why these conformational isomers are given special study ("conformational analysis") is because they "can be used to predict and explain product selectivity, mechanisms, and rates of reactions". Substituted alkenes and cycloalkanes can exist as configurational isomers. Let’s put this chart flow and start from the concept of isomerism in general: Iso- means same, so, in order for any two molecules to be isomers, they must have the same chemical formula.

Sharing on What is the difference between cis and trans isomers? Lab 4: Distillation. Conformational isomerism arises when the rotation about a single bond is relatively unhindered. Actually, geometrical and optical isomerism are together Conformational Isomers Up to this point, all of our molecular depictions have focused on keeping track of the electrons around each atom and the connectivity of the atoms themselves. It is important to be able to recognise isomers because they can have different chemical, physical properties and biological properties. A form of stereoisomerism where interconversions of isomers are possible by rotations referring to single bonds is called as Conformational Isomerism. An isomer which is due to the rotatability of carbon-carbon single bonds (transitory). Conformational isomers have the atoms bonded in the same way as each other, but the 3D structure differs.

Epimers vs Isomers. Configurational isomers have the same molecular formula and the same bonds. Unlike constitutional and configurational isomers, conformational isomers cannot be separated. This type of isomerism is found mainly in Alkanes and rarely in alkanes. However, some of the atoms are arranged differently in space with respect to each other, and the isomers cannot be interconverted without breaking a covalent bond. However, the carbon-hydrogen bonds of methane constantly vibrate and bend, so that on very short timescales an apparent isomerism can be said to exist. Configurational isomers are stereoisomers that do not readily interconvert at room temperature and can (in principle at least) be separated.
