Two molecules are enantiomers if they are non-superimposable mirror images of each other. This means that they have the same atoms but arranged in a different spatial orientation. One way to determine if two molecules are enantiomers is to compare their three-dimensional structures and see if they are mirror images of each other.

Why are enantiomers of biological interest?
Mainly because enantiomers have identical physical and chemical properties. However, the difference between two enantiomers can have tremendous impact, especially in biological systems, because many important biological molecules are chiral.
How many chiral carbon have butaclamol?
Butaclamol has one chiral carbon, which means it can exist as two enantiomers.
What is Invertomerism?
In case of trivalent N, the molecules are pyraMIDAL in nature.one of the orbitals is occupied by the lone pair of electrons.now, due to vibration in the molecule along the axis perpendicular to the bond axis ,the molecules are inverted and the two forms remain in equilibrium state .these two forms are non superimposablemirror images(showing enantiomerism) --- this phenomenon of trivalent n compounds are known as INVERTOMERISM
What is the difference between enantiomers and diastereomer?
There can be several structural formulas for a single molecular formula. These are known as isomers. Isomers can be defined as "different compounds that have the same molecular formula." There are mainly two types of isomers called constitutional isomers and stereoisomers. For example, C4H10 can have following constitutional isomers.Constitutional isomers are "isomers that differ because their atoms are connected in a different order." Stereoisomers are isomers that differ from the spatial arrangement of the atoms. Diastereomers and enantiomers are the two types of stereoisomers.DiastereomersDiastereomers are stereoisomers whose molecules are not mirror images of each other. For example, cis and trans isomers are Diastereomers.In the above two compounds, the connectivity of atoms is same. Both compounds have a carbon- carbon double bond. And for each carbon, a chlorine atom and a hydrogen atom is connected. Cis and trans molecules differ only from the way atoms are arranged in the space. That is, in cis isomer, both hydrogens are on the same side of the carbon double bond. But in the trans isomer, hydrogen atoms are on either side of the carbon double bond. And the two structures are not mirror images of each other. Therefore, they are Diastereomers. However, cis and trans molecules are not the only kind of diastereomers we can find.EnantiomersEnantiomers are "stereoisomers whose molecules are nonsuperposable mirror images of each other. " Enantiomers are only possible with molecules, which are chiral. Chiral molecule is the one that is not identical with its mirror image. For a molecule to be chiral, it should have one tetrahedral atom with four different groups attached to it. This carbon atom is known as a stereocenter. Chiral molecules make mirror images that are not superposable. So the molecule and the mirror image are said to be enantiomers. Following is an example of a compound that forms enantiomers.The enantiomers are named using the R and S system. So, according to the system the molecule on the right hand side is (S)-2-butanol, and the other one is (R)-2-butanol. Enantiomers don't have different boiling points, melting points, solubilities, different infrared spectra etc. All these chemical and physical properties of enantiomers are similar because intermolecular forces are similar in both isomers. They become separate only by their different behaviors towards the plane polarized light. That is, enantiomers rotate the plane of the plane polarized light in opposite directions. However, they rotate the light in equal amounts. Because of their effect on the polarized light, enantiomers are said to be optically active. The equimolar mixture of two enantiomers is called a racemic mixture. Racemic mixture doesn't show any rotation of the polarized light, therefore it is optically inactive.
How can one determine the stereoisomers of a molecule?
One can determine the stereoisomers of a molecule by examining its three-dimensional structure and identifying any differences in the spatial arrangement of atoms or groups around a chiral center. Stereoisomers are molecules that have the same molecular formula and connectivity of atoms, but differ in their spatial arrangement. There are two main types of stereoisomers: enantiomers, which are mirror images of each other, and diastereomers, which are not mirror images. Analyzing the molecule's structure and considering factors such as chirality, symmetry, and conformation can help in identifying and distinguishing between different stereoisomers.
What is racemic mixture?
A racemic mixture is a combination of equal amounts of two enantiomers, which are molecules that are mirror images of each other but cannot be superimposed. This results in a mixture that is optically inactive, as the optical activities of the two enantiomers cancel each other out. Racemic mixtures are common in pharmaceuticals, where one enantiomer may have the desired therapeutic effect while the other may be inactive or even harmful. The process of separating enantiomers from a racemic mixture is known as resolution.

How the two enantiomers are separated?
Enantiomers can be separated using techniques like chiral chromatography, which utilizes a chiral stationary phase to separate the enantiomers based on their differing interactions. Another method is through the use of chiral derivatizing agents that can convert the enantiomers into diastereomers, which can then be separated using traditional chromatography techniques.
What does the term enentiomers means?
Enantiomers are molecules that are mirror images of each other. Also known as optical isomers. The two forms are different in the way that left- and right-hand gloves are different.

What is the difference between racemic mixture and mesocompounds?
1:1 molar solution of two enantiomers is recemic mixture and it may be resolved into two parts by chemical means while mesoform is a pure substance and can not be resolved, but both these are optically inactive.
What is A mixture of equal amounts of two enantiomers?
its called a racemic mixture and is optically inactive
Will all enzymes react the same way with two enantiomers?
no, enzymes are very specific with respect to stereo-chemistry and usually is active only to one enantiomer
What are enantiomers with monosaccharides as an example?
Enantiomers are a type of stereoisomer that are non-superimposable mirror images of each other, often found in compounds with chiral centers. In the context of monosaccharides, such as glucose, enantiomers differ in the arrangement of atoms around one or more chiral carbon atoms, resulting in two distinct forms—D-glucose and L-glucose. These enantiomers have identical physical properties, except for their interaction with polarized light and their biological activities, which can differ significantly. The distinction between D and L forms is crucial in biochemistry, as enzymes often recognize only one enantiomer for metabolic processes.
