ummm, i dont understand what ur asking, but if u wanna know how its generated, it has something to do with positive ions of a molecule flowing in one direction, and negative ions flowing in either the same of opposite direction forming direct and indirect currents, or at least that's what i think it is

Geometrical isomerism (Cis and trans)is not shown on the compound you ask for, if you ask about an alkene(carbon,carbon double bond ) i.e 1,4-dichlorohexene the sturcure is (Cl)CH2-CH2=CH2-CH2(Cl)CH2CH3.

Bromine would add to the double bond in the ring and to the double bonds in the methyl-vinyl group adjacent to the ring.\n\nIt would create 2 stereocenters and it would be racemic, because bromine is not enantioselective.

In optics, optical rotation or optical activity is the rotation of linearly polarized light as it travels through certain materials. It occurs in solutions of chiral molecules (e.g. sugar), solids with rotated crystal planes (e.g. quartz), and spin-polarized gases of atoms or molecules. It is used in sugar industry to measure syrup concentration, in optics to manipulate polarization, in chemistry to characterize substances in solution, and is being developed as a method to measure blood sugar concentration in diabetic people.

enantiomeric excess (%) = \n(specific rotation of the mixture/ specific rotation of the pure enantiomer in excess)*100 \n\nor \n\nenantiomeric excess (%) = \n( | [enantiomer 1] - [enantiomer 1] | ) /([enantiomer 1] + [enantiomer 1] *100 \n\nwhere the square brackets indicate concentrations, and the | -- | in the numerator means "absolute value".

Once the hydroxyl group leaves the alcohol, the structure would lose its pyramidal shape and flatten into a two-dimensional shape.  The halide ion would add from either side, having a 50% chance of attaching from either side.  Once halogenated, the new molecule would again be optically active but you would have an equal abundance of both R and L enantiomers.  This follows one of the rules of stereochemistry in that optically inactive reactants (in this case HX) always yield optically inactive products.

isomerism is classified into structural and stereo\nstuctural isomerism arises b/w two compounds when they differ in the structural arrangement of atoms. in organic it is divided into:\nchain\nposition\nfunctional\nmeta\nhowever in inorganic chemistry we have other classifications\n\nfor more and detailed information, u could go to google

Then defend it... I say that there is no way that a random chance process could have formed life forming proteins and DNA with their unique chirality. If proteins and DNA were formed by chance  each and every one of the components would be a 50/50 mixture of the two optical isomers. This is not what we see in natural proteins or in natural DNA. How can a random chance natural process create proteins with thousands of "L" molecules, and then also create DNA with billions of "R" molecules? Does this sound like random chance or a product of design? Even if \nthere were a magic process to introduce chirality, it would only create one isomer. If such a process existed, we do not know anything about it or how it would work. If it did exist, how were compounds with the other chirality ever formed? Even if there were two magical processes, one for each isomer, what determined which process  was used and when it was used, if this was a random chance natural process? The idea of two processes requires a controlling mechanism, and this kind of control is not possible in a random chance natural process.\nYou are an intelligent man alot smarter than a mere theist so I don't think I need to explain chirality more thoroughly. You just need to defend your statement... Too bad you can't now that you have this informant ion.....   Jim

Since you made your question sound real with intent on getting an answer even if you don't except it I will try to explain.\nArthur Conan Doyle for his character Sherlock Holmes wrote and I quote loosely.. "You solve a mystery by removing posiblities. What ever is left no matter how improbable is the truth.."\nThat leads me to chirality. Although two chemical molecules may appear to have the same elements and similar properties, they can still have different structures. When two molecules appear \nidentical and their structures differ only by being mirror images of each other, those molecules are said to have chirality. Your left and right hands illustrate chirality. When a random chemical reaction is used to prepare molecules having chirality, there is an equal opportunity to prepare the left-handed isomer as well as the right-handed isomer. It is a scientifically verifiable fact that a random chance process, which forms a chiral product, can only be a 50/50 mixture of the two optical isomers. There are no exceptions. Chirality is a property that only a few scientists would even recognize as a problem. The fact that chirality was missing \nin those amino acids is not just a problem to be debated, it points to a catastrophic failure that "life" cannot come from chemicals by natural processes. If proteins and DNA were formed by chance, each and every one of the components would be a 50/50 mixture of the two optical isomers. This is not what we see in natural proteins or in natural DNA. How can a random chance natural process create proteins with thousands of "L" molecules, and then also create DNA with billions of "R" molecules? Does this sound like random chance or a product of design? Chirality is not just a major problem for evolution; it is a dilemma. It is this handedness that gives DNA the spiral shaped helical structure. If one molecule in the DNA structure had the wrong chirality, DNA would not exist in the double helix form, and DNA would not \nfunction properly. The entire replication process would be derailed like a train on bad railroad tracks. In order for DNA evolution to work, billions of molecules within our body would have to be generated with the "R" configuration all at the \nsame time, without error. If it is impossible for one nucleotide to be formed with chirality, how much less likely would it be for billions of nucleotides to come together exactly at the same time, and all of them be formed with the same chirality? According to evolution, natural processes must explain everything over long periods of time. However, the process that forms chirality cannot be explained by natural science in any amount of time.\nThis is evidence straight from the labs of Science. The Bible has nothing to do with these facts. Yet the magnitude of the problem indicates that there WAS a creative force behind all life and that the spontaneous life generation that most scientist hold up as fact is at best far fetched and worst impossible.....

Is it possible you're not spelling it correctly?  Perhaps the following will help...\n"A bioisostere is a compound resulting from the exchange of an atom or of a group of atoms with another, broadly similar, atom or group of atoms. The objective of a bioisosteric replacement is to create a new compound with similar biological properties to the parent compound. The bioisosteric replacement may be physicochemically or topologically based. "\n(From the ChemiCool website.)

An optically active compound (rotate the light) must be  a chiral, and this property is belong chiral compounds only.Anantiomers play a vital role in living systems .

Liquid crystals are substances that exhibit a phase of matter that has properties between those of a conventional liquid, and those of a solid crystal. For instance, a liquid crystal (LC) may flow like a liquid, but have the molecules in the liquid arranged and oriented in a crystal-like way. There are many different types of LC phase, which can be distinguished based on their different optical properties (such as birefringence). When viewed under a microscope using a polarized light source, a liquid crystal material will appear to have a distinct texture. Each 'patch' in the texture corresponds to a domain where the LC molecules are oriented in a different direction. Within a domain, however, the molecules are well ordered. Liquid crystal materials may not always be in an LC phase (just as water is not always in the liquid phase: it may also be found in the solid or gas phase). Liquid crystals can be divided into thermotropic and lyotropic LCs. Thermotropic LCs exhibit a phase transition into the LC phase as temperature is changed, whereas lyotropic LCs exhibit phase transitions as a function of concentration.

Its called a "Chimera"\n\nIn response to the response below about tetraploidy.  Tetraploidy is highly lethal.  The person asking the question is referring to a tv show where there are people who have "two sets of chromosomes."  Not two identical sets in the same cell that didn't undergo mitosis correctly (and maybe meiosis).  The question is asking about people who have their "twin inside of them."  A condition where a fraternal twin egg is ingulfed by the other egg resulting in a chimera.  Check the references:
