What is stereochemical structures?
Stereochemical structures refer to the three-dimensional arrangement of atoms in a molecule. They include configurations such as cis-trans isomerism, optical isomerism, and geometric isomerism, which affect the physical and chemical properties of the molecule. Knowledge of stereochemical structures is important in understanding the reactivity and behavior of organic compounds.
What are stuctural isomerism?
Structural isomerism is a type of isomerism where the isomers have the same molecular formula but differ in the connectivity of atoms within the molecule. This results in different structural arrangements and different chemical and physical properties among the isomers. There are different types of structural isomerism, such as chain isomerism, positional isomerism, and functional group isomerism.

How do alkenes show geometric isomerism?
Alkenes show geometric isomerism when they have restricted rotation around the double bond, leading to different spatial arrangements of atoms. This can occur when two different groups are attached to each carbon of the double bond, resulting in cis-trans isomerism.
Why is isomerism not found in propane?
Isomerism is a phenomenon where compounds have the same chemical formula but different structural arrangements. Propane (C3H8) consists of three carbon atoms bonded in a straight chain with eight hydrogen atoms attached. Since there are no other possible ways to arrange the carbon atoms, propane does not exhibit isomerism.
Why an organic compound is able to show optical isomerism but not geometrical isomerism?
Optical isomerism arises due to the presence of chiral centers in a molecule, which leads to the molecule being non-superimposable on its mirror image. Geometrical isomerism, on the other hand, arises from restricted rotation around a double bond or ring. Organic compounds can exhibit optical isomerism if they have chiral centers but typically do not show geometrical isomerism unless there are specific structural features like double bonds or rings that limit rotation.
Which amino acid does not show any optical isomerism?
Glycine is the only amino acid that does not show any optical isomerism because it does not have a chiral carbon atom, which is necessary for optical isomerism to occur. Glycine has two hydrogens attached to its alpha carbon, making it achiral.
What is the difference between geometrical and optical isomerism?
Geometrical isomerism arises due to the restricted rotation around a bond, resulting in different spatial arrangements of atoms. Optical isomerism, on the other hand, arises due to the presence of chiral centers, leading to molecules that are non-superimposable mirror images of each other (enantiomers).
What type of isomer for C2H2Br2?
Probable you think to CH2Br2, dibromomethane.

Optical isomerism in aldehydes and ketones?
The carbonyl group present in aldehydes or ketones itself is optically inactive but if a carbon attached to carbonyl group is asymmetric (attached to four different groups or atoms) then such compound may show to enantiomers as there are two enantiomers of CH3-CHCl-CHO.
Why are CH3CH2COOH and CH3CHOHCHO optical isomers?
CH3CH2COOH and CH3CHOHCHO have chiral centers, which are carbon atoms bonded to four distinct groups. Their mirror images are non-superimposable. This asymmetry results in optical isomerism, where the molecules exist as enantiomers.
What is the another name of geometric isomers?
Geometric isomerism also known as cis-trans isomerism or E-Z isomerism
Is cis-trans isomerism included in geometrical isomerism?
The geometrical isomerism is mainly Cis-trans isomerism but in some cases we use another term Z and E isomers, they are almost same.
What are stuctural isomerism?

Why elctrovalent compound does not show the isomerism while covalent compound show isomerism?
Nt sure I agree with the question. Consider the octahedral polyatomic ion Co(NH3)4Cl2+ this has trans and cis isomers (chlorines opposite each other at 180 0 or next to each other at 90 0). Generelly isomerism is rare in electrovalent compounds. One interesting example is the optical isomerism of ammonium sodium tartrate discovered by Pasteur.
