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.
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.
What is meant by isomerism and what are the types of isomerism?
Isomerism is the phenomenon in which two or more compounds have same molecular formula but their structural formula is different. The compounds are called Isomers.There are 2 types of isomerism.1) Structural Isomerism which is further classied into 5 more types of isomerisms:i) Chain Isomerism which is due to difference in nature or the carbon chain e.g. isopentane, neopentane or n-pentaneii) Position isomerism which is due to the difference in position of the functional group or unsaturated linkage in the same carbon chain. e.g. 1-Chloropropane is the isomer or 2-chloropropane or another example is 1-butene which is isomer of 2-buteneiii) Functional group isomerism in which there are different functional group but same molecular formula. e.g. dimethyl ether is functional group isomer of ethyl alcoholiv) Metamerism is due to the unequal distribution of carbon atoms on either side of the functional group and such compounds belong to same homologous series. e.g. diethyl ether and methyl n-propyl ether are metamers.dietheyl ether: CH3 - CH2 - O - CH2 - CH3methyl n-propyl: CH3 - O - CH2 - CH2 - CH3v) Tautomerism due to shifting of proton from one atom to other in the same molecule.The 2nd type of isomerism is Cis-trans Isomerism or geometric isomerism and compounds who possess same structural formula but differ with respect to the positions of the identical groups in space are called cis-trans isomers and the phenomenon is cis-trans or geometric isomerism.

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 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.
What type of isomer for C2H2Br2?
Probable you think to CH2Br2, dibromomethane.
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.
Optical isomerism in aldehydes and ketones?

What are the importance of optical isomerism in pharmacy?
Optical isomerism is important in pharmacy because enantiomers of a drug may have different pharmacological properties, such as potency or side effects. This can impact the effectiveness and safety of a medication for a patient. Understanding and controlling optical isomerism is crucial for ensuring that patients receive the most appropriate treatment.

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.
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.
Why does covalent compound exhibit isomerism?
Covalent compounds exhibit isomerism because they have the same chemical formula but different structural arrangements of atoms. This results in different physical and chemical properties for each isomer. Isomerism in covalent compounds is often due to differences in the connectivity or spatial arrangement of atoms within the molecule.
