Which is/are true regarding pair of geometrical isomers?a)They are non...
a) Geometric isomerism occurs when two structures with the same connectivity are not inconvertible.
b) The boiling points of the isomers might be different enough that you can separate them by fractional distillation. The affinities for the stationary phase may be different enough that they can be separated by gas chromatography.
c) Geometric isomers are diastereomers, i.e. they are stereoisomers that are not enantiomers. The prefixes cis and trans refer to the relative dispositions of the substituents attached to the doubly bonded carbon atoms. In the cis diastereomer the hydrogen atom attached to one carbon is on the same side of the double bond as the hydrogen attached to the other carbon. In the trans stereoisomer they are on opposite sides.

Geometrical isomers:
Geometrical isomers are a type of stereoisomers that have the same molecular formula and connectivity but differ in the spatial arrangement of their atoms due to the presence of a double bond or a ring structure. They can exist in two or more different arrangements, known as cis and trans isomers.
A) They are non-interconvertible by rotation:
This statement is true. Geometrical isomers cannot interconvert by simple rotation around a single bond. The double bond or ring structure restricts the rotation, resulting in different spatial arrangements. The cis and trans isomers have different physical and chemical properties.
B) They can be separated by fractional distillation:
This statement is also true. Fractional distillation is a separation technique used to separate compounds based on their boiling points. Geometrical isomers may have different boiling points due to their different molecular arrangements. Therefore, it is possible to separate them using fractional distillation.
C) They are also a pair of diastereomers:
This statement is true. Diastereomers are a type of stereoisomers that have different spatial arrangements at one or more chiral centers but are not mirror images of each other. Geometrical isomers can be considered as a special case of diastereomers where the difference in spatial arrangement arises due to the presence of a double bond or ring structure.
D) They may have an axis of symmetry but must not contain a plane of symmetry:
This statement is not true. Geometrical isomers may or may not have an axis of symmetry or a plane of symmetry. It depends on the specific arrangement of atoms and groups around the double bond or within the ring structure. Some geometrical isomers may have symmetry elements, while others may not.
In summary, the correct options regarding pair of geometrical isomers are A) They are non-interconvertible by rotation, B) They can be separated by fractional distillation, and C) They are also a pair of diastereomers.
