Isomerism

What is the syn and anti form of a compound?

Geometrical isomerism is exhibited by but-$2$-ene.

Describe the cis- and trans- form of but-$2$-ene.

Enantiomers are two substances that are mirror images of each other and are non-superimposable.

Describe optical isomerism.

A stereoisomerism is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms but differ in the three-dimensional orientations of their atoms in space.

Describe stereoisomerism.

Metamerism arises due to the unequal distribution of alkyl groups on either side of the functional groups in the molecules.

Define metamerism in organic chemistry.

Two or more compounds with different molecular formulae, but same functional groups are called functional isomers and this phenomenon is termed functional isomerism.

Describe functional isomerism:

When two or more compounds with the same molecular formula differ in the position of substituent atom or functional group on the carbon atom, they are called position isomers and this phenomenon is termed position isomerism.

Describe position isomerism.

Chain isomerism is the phenomenon in which two or more compounds have the same molecular formula but have differences in the arrangement of carbon atoms in straight or branched chains.

Describe chain isomerism.

There are eight isomers of hexane.

Give all the isomers of hexane.

The key difference between structural isomers and stereoisomers is that the structural isomers have the same chemical formula, but different atomic arrangements, whereas the stereoisomers have the same chemical formula and atomic arrangement, but different spatial arrangements.

List the types of isomerism in organic chemistry.

Isomerism is the phenomenon in which more than one compounds have different molecular formula.
