What Are Geometrical Isomerism? Explain Them With An Example?

Answer:
hii
your answer is here !
Explanation:
Geometrical isomerism is an example of stereo-isomerism.
This occurs when substances have the same molecular formula, but a different arrangment of their atoms in space. There are three ways that this can happen:
-> where there is a C=C bond in the molecule
-> where a molecule has rings; or
where there is a >C=N bond.

Your Answer..
Geometric isomers are chemical species with the same type and quantity of atoms as another species, yet having a different geometric structure. Atoms or groups exhibit different spatial arrangements on either side of a chemical bond or ring structure. Geometric isomerism is also called configurational isomerism or cis-trans isomerism. Note cis-trans isomerism is a different description of geometry than E-Z isomerism.
The terms cis and trans are from the Latin words cis, meaning "on this side". and trans, meaning "on the other side". When substituents are both oriented in the same direction as each other (on the same side), the diastereomer is called cis. When the substituents are on opposing sides, the orientation is trans.Cis and trans geometric isomers exhibit different properties, including boiling points, reactivities, melting points, densities, and solubilities. Trends in these differences are attributed to the effect of the overall dipole moment. The dipoles of trans substituents cancel each other out, which the dipoles of cis substituents are additive. In alkenes, trans isomers have higher melting points, lower solubility, and greater symmetry than cis isomers.
