What are the differences between enantiomers, diastereomers, and identical molecules in terms of their stereochemistry?
Enantiomers are mirror images of each other and have opposite configurations at all chiral centers. Diastereomers are stereoisomers that are not mirror images and have different configurations at some, but not all, chiral centers. Identical molecules have the same configuration at all chiral centers and are the same molecule.

What is difference between epimers and enantiomers?
Epimers are diastereoisomers that differ in the configuration at one stereocenter, while enantiomers are mirror images of each other with opposite stereochemistry at all stereocenters. Epimers have different physical and chemical properties, while enantiomers have identical physical and chemical properties except for their interaction with plane-polarized light.
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.
What is the difference between enantiomers and identical molecules?
Enantiomers are mirror images of each other, like left and right hands, while identical molecules are the same in structure and properties.
What is the stereochemistry of 2,3-dibromobutane?
The stereochemistry of 2,3-dibromobutane is meso because it has a plane of symmetry that divides the molecule into two identical halves.
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.

Can CH4 exist as a pair of enantiomers?
No, CH4 (methane) cannot exist as a pair of enantiomers. Enantiomers are non-superimposable mirror images of chiral molecules, which require a carbon atom with four different substituents. Since methane has four identical hydrogen atoms attached to a single carbon atom, it lacks the necessary asymmetry to form enantiomers.
How are enantiomers related to each other?
Enantiomers are non-superimposable mirror images of each other, meaning they are identical in physical and chemical properties except for how they interact with other chiral molecules. They have opposite configurations at every chiral center and rotate plane-polarized light in opposite directions.
Do identical offspring show differences in phenotype?
Yes, identical offspring can show differences in phenotype due to environmental factors, epigenetic modifications, or random developmental variations. While identical twins share the same genetic information, differences in experiences and exposures can lead to variations in how genes are expressed, resulting in phenotypic differences.
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.
Can genetically identical offspring show differences in phenotype?
They always do.

Religion, after that they are identical.
