A beacause diasteromers are isomers which are not mirror images of each other while enatiomers are those which are mirror images of each other 2geometric isomers which are not mirror image of each other will be diasteromers nd enatiimers

Geometrical isomers are a type of stereoisomers that have different spatial arrangements due to the presence of a double bond or a ring in a molecule. They cannot be interconverted by rotation around a single bond and therefore have different physical and chemical properties. Geometrical isomers can be classified into diastereomers or enantiomers.

Diastereomers:
Diastereomers are stereoisomers that are not mirror images of each other and have different physical properties. In the case of geometrical isomers, diastereomers occur when there are two different groups attached to each carbon atom of the double bond or ring. These different groups can be on the same side of the molecule (cis) or on opposite sides (trans). Since diastereomers have different physical and chemical properties, they can be separated by techniques such as chromatography or crystallization.

Enantiomers:
Enantiomers are stereoisomers that are non-superimposable mirror images of each other. In the case of geometrical isomers, enantiomers occur when there are two identical groups and two different groups attached to each carbon atom of the double bond or ring. The spatial arrangement of these groups can lead to two different enantiomeric forms. However, for geometrical isomers, enantiomers are not possible as there is no chiral center present in the molecule.

Structural Isomers:
Structural isomers, also known as constitutional isomers, are molecules with the same molecular formula but different connectivity of atoms. They have different physical and chemical properties due to their different structural arrangements. Geometrical isomers are a type of structural isomers as they have different spatial arrangements due to the presence of a double bond or a ring.

Interconvertible at Room Temperature:
Geometrical isomers are not interconvertible at room temperature as they require breaking and reforming of chemical bonds. The double bond or the ring restricts the rotation around the bond, leading to the stability of the isomers. Therefore, they exist as separate entities with their own distinct properties.

In conclusion, geometrical isomers can be classified as diastereomers or enantiomers. They are a type of structural isomers that have different spatial arrangements due to the presence of a double bond or a ring. Geometrical isomers cannot be interconverted at room temperature and have different physical and chemical properties.
