Organic Enantiomers [1]
Stereoisomers are a type of isomer where the order of the atoms in the two molecules is the same but their arrangement in space is different. The two main types of stereoisomerism are diastereomerism (including ‘cis-trans isomerism’) and optical isomerism (also known as ‘enantiomerism’ and ‘chirality’)
Every stereocenter in one isomer has the opposite configuration in the other. They share the same chemical structure and chemical bonds, but differ in the three-dimensional placement of atoms so that they are mirror images, much as a person’s left and right hands are
The amino acid alanine is example of an entantiomer. The two structures, D-alanine and L-alanine, are non-superimposable
[Solved] Which of the following compounds can exist as optical isomer [2]
Which of the following compounds can exist as optical isomers?. – Two images are said to be superimposable on each other if their corresponding parts coincide when one is placed upon the other.
– When two isomers rotateplane polarised light in different directions, then they are known as optical isomers.. – Absence of centre of Symmetry- when a line is drawn from the centre of a molecule towards the corner of each atom, it should not encounter similar atoms.
– Presence of Chiral centre-An object or molecule which has no plane of symmetry and is not superimposable on its mirror image is said to be chiral or dissymmetric.. Let us examine the given molecules for chiral centres

Optical Isomers [6]
Optical isomers are two compounds which contain the same number and kinds of atoms, and bonds (i.e., the connectivity between atoms is the same), and different spatial arrangements of the atoms, but which have non-superimposable mirror images. Each non-superimposable mirror image structure is called an enantiomer
Not all coordination compounds have optical isomers.. Note that the molecule on the right is the reflection of the molecule on the left (through the mirror plane indicated by the black vertical line)
Pure samples of enantiomers have identical physical properties (e.g., boiling point, density, freezing point). Chiral molecules and ions have different chemical properties only when they are in chiral environments.
Optical Isomerism in Organic Molecules [7]
This page explains what stereoisomers are and how you recognize the possibility of optical isomers in a molecule.. Isomers are molecules that have the same molecular formula, but have a different arrangement of the atoms in space
Where the atoms making up the various isomers are joined up in a different order, this is known as structural isomerism. Structural isomerism is not a form of stereoisomerism, which involve the atoms of the complex bonded in the same order, but in different spatial arrangements
Optical isomers are named like this because of their effect on plane polarized light. Simple substances which show optical isomerism exist as two isomers known as enantiomers.

optical isomerism [9]
This page explains what stereoisomers are and how you recognise the possibility of optical isomers in a molecule.. Isomers are molecules that have the same molecular formula, but have a different arrangement of the atoms in space
Where the atoms making up the various isomers are joined up in a different order, this is known as structural isomerism. Structural isomerism is not a form of stereoisomerism, and is dealt with on a separate page.
In stereoisomerism, the atoms making up the isomers are joined up in the same order, but still manage to have a different spatial arrangement. Optical isomers are named like this because of their effect on plane polarised light.

Optical isomerism is a case where the isomers display identical characteristics in terms of molecular weight as well as chemical and physical properties. However, they differ in their effect on the rotation of polarized light.
All waves vibrating in a single plane are referred to as plane parallel or plane-polarized.. Chiral and achiral molecules are used to describe the symmetry characteristics of molecules
Superimposable and Nonsuperimposable Nature of Chiral and Achiral Objects. Here are the details with examples of Chiral and Achiral Objects
a. Which of the following compounds can exist as cis–trans isomer… [11]
Which of the following compounds can exist as cis–trans isomers? 1. This video solution was recommended by our tutors as helpful for the problem above.
Stereoisomerism [12]
In stereochemistry, stereoisomerism, or spatial isomerism, is a form of isomerism in which molecules have the same molecular formula and sequence of bonded atoms (constitution), but differ in the three-dimensional orientations of their atoms in space.[1][2] This contrasts with structural isomers, which share the same molecular formula, but the bond connections or their order differs. By definition, molecules that are stereoisomers of each other represent the same structural isomer.[3]
Every stereogenic center in one has the opposite configuration in the other. Two compounds that are enantiomers of each other have the same physical properties, except for the direction in which they rotate polarized light and how they interact with different optical isomers of other compounds
Pure enantiomers also exhibit the phenomenon of optical activity and can be separated only with the use of a chiral agent. In nature, only one enantiomer of most chiral biological compounds, such as amino acids (except glycine, which is achiral), is present

Isomers [14]
This chapter addresses three main forms of isomerism: structural, optical, and geometric isomerism. Isomers are molecules that have the same chemical formula but different structures
You will also learn to identify optical isomers, which occur when stereocenters, or tetrahedral carbons with four different substituent groups, are present in a molecule. Enantiomers can be differentiated by the configuration of substituent groups around their stereocenters
The objective of this section is to introduce you to constitutional isomers using alkanes.. Two molecules which have the same molecular formula but different structural formulas, or bonding arrangements, are known as constitutional isomers.
Calculate total number of optical isomers in the following compound CH3(CHOH)3CH3 ?? [15]
Calculate total number of optical isomers in the following compound CH3(CHOH)3CH3 ??. In this compound there are 4 optical isomers; this is calculated by multiplying the number of chiral centres by two.
A chiral centre is a carbon atom that is bonded to four different molecules or atoms. Each chiral centre will result in two different optical isomers.
Then, just multiply the number of chiral centres by two to give the number of optical isomers.. So below is your molecule (I have used MolView to sketch this):
Chirality2 [16]
Most of the examples we considered involved molecules which. structures which contain two or more chiral centers
ago, Louis Pasteur noticed that a sample of sodium ammonium tartrate,. a salt of tartaric acid used in wine making, contained two
that Pasteur examined contained two chiral carbon atoms. a compound that contains n chiral atoms can exist in 2n
What are the essential conditions for optical isomerism? [17]
What are the essential conditions for optical isomerism?. Hint: As we know that the optical isomers are those two compounds that contains the same number of atoms having similar kinds of elements and bonds within the same atom but there is different arrangement of atoms which is non- superimposable mirror image and this property is called optical isomerism.
And the optical isomerism which is basically a property of compounds displaying identical characteristics in terms of chemical and physical properties but differ in their orientation and rotation of polarised light.. So, the essential conditions for optical isomerism are as follows:
II.They should possess similar molecular formulas as well as similar structural formulas.. III.The compound must possess an asymmetric carbon atom which is bonded to four different groups of atoms or molecules which is normally called chiral carbon.
