Restricted rotation of the carbon-carbon double bond.
no for cis trans isomerism to exist, 2 conditions must be fufilled. firstly, there must be restricted rotation about the double bond. Secondly, there must be 2 different substituent groups attached to each carbon atom. In 1-pentene, one of the carbon has 2 hydrogen attached to it, thus it does not fufill the second condition. Hence, 1-pentene does not exhibit geometrical isomerism(cis-trans)
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.
A tetrahedral complex of the type MA2B2 does not show geometrical isomerism because the ligands are the same and located in identical positions relative to the metal center, resulting in the same spatial arrangement. Geometrical isomerism arises when there is restricted rotation around a bond, leading to different spatial arrangements of ligands.
Electrovalent compounds, also known as ionic compounds, do not show isomerism because their structure is determined by the arrangement of oppositely charged ions rather than the orientation of atoms. Isomerism requires a different arrangement of atoms in a molecule, which is not possible in ionic compounds as they exist as a three-dimensional array of ions held together by strong electrostatic forces.
Ionic compounds do not exhibit isomerism because the ions in an ionic compound are arranged in a specific ratio dictated by their charges to maintain overall electrical neutrality. The fixed arrangement of the ions in an ionic compound does not allow for the rearrangement of atoms or groups that is necessary for isomerism to occur.
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.

2-butene show geomatric isomerism because each double bond carbon atom has two different group
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.
This is only one compound and does not show isomerism.

Geometric isomerism also known as cis-trans isomerism or E-Z 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.
Ionic compounds do not exhibit isomerism because the ions in an ionic compound are arranged in a specific ratio dictated by their charges to maintain overall electrical neutrality. The fixed arrangement of the ions in an ionic compound does not allow for the rearrangement of atoms or groups that is necessary for isomerism to occur.
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.
