What are geometric isomers?

also called Isomer Cis-Trans, geometric isomer is a type of stereoizomer that has two states. Isomers are molecules that have the same molecular formula, but differ in their molecular structure. Stereoisomer is a type of isomer in which atoms occur in the same order, but are still structurally different. In the case of geometric isomers, the molecules create either the shape of the staircase or the shape of the U.

, which are commonly found in the dual-coated double molecules that have geometric isomers in any substance that has two central atoms with double or triple bond. Individual bonds, created by two atoms sharing electron, allow the molecules on their axis called free rotations. The rotation of free rotation allows different structural molecules configurations, although the atoms are connected in exactly the same way. Molecules with one binding of central atoms that show different structures.

double bonds created by two atoms sharing two electrons, neuThey are possible to rotate free rotation. Because their rotation is limited, double bond molecules cannot circle and create different shapes, so those that have different structural arrangements are structurally different molecules. In geometric isomers, the atom - or more often a group of atoms - is bound to each of the central atoms. This creates two types of structures.

The first group of atoms is connected to the central atom in the same place for both atoms, so each side of the molecule is a mirror image of the second. This creates a shape molecule or isomer cis. In the second structure, groups of atoms are connected to opposite places on central molecules and create a staircase structure.

For example, the simplest geometric isomers are bet-2-en, isomers of gas buten, which is found in oil. Buten, C _{4 h 8 has four isomers, two of which are geometric isomers. Central atoms in buT-2-ENu are a dual binding carbon. Each carbon atom is connected by hydrogen atom and molecule ch 3 . In CIS --- 2, there are molecules of ch 3 placed on the same side of each carbon atom, which forms the shape of the U. in the trans-but-2 -ne, the molecules are located on the opposite sides and create the shape of the staircase.}

geometric isomers behave differently apart. For example, CIS and Trans-2-Ene, have different boiling points and melting. The temperature at which the isomer cis 39.2 ° C (4 ° C) and its melting temperature is -218 ° F (-139 ° C), while the trans isomer will boil at 33.8 ° F (1 ° C) and melt at -157 ° F (-105 ° C).
