Answer (1 of 3): One good starting point in figuring out this type of problem would be determine the degree of unsaturation. Two example isomers of C4H8 are: Other alkenes having the C4H8 are 2-butene and methylpropene. Hydrocarbon structures and types of isomerism (structural isomers, cis/trans isomers, and enantiomers). (a . So they are positional isomers. The last one is the functional isomer, in which there is a difference between the type of functional group which is present in the molecule. Butene Isomers. However, based on the isomer counts, I assumed you are in correct track but originally thought you might have counted meso-isomer twice (as two stereoisomers) for the total count. Isomers are compounds with different physical and chemical properties but the same molecular formula. Each doubly bonded carbon has to form bonds with other atoms or groups to satisfy its tetravalent nature.
In organic chemistry, there are many cases of isomerism. The isomer in which the two chlorine (Cl) atoms lie on the same side of the molecule is called the cis isomer (Latin cis, meaning "on this side") and is named cis-1,2-dichloroethene. siegel (x3950) or dr. Ford V10 Fuel Economy Chip.
0 votes . Positional isomers or regioisomers differ from each other based on the position at which the functional group is attached to the molecule. ChEBI ID.
