There are two isomers for dibromopropane: 1,2-dibromopropane and 2,2-dibromopropane.
For the molecular formula C5H10, the cyclic structural isomers include cyclopentane, 1-methylcyclobutane, and 2-methylcyclobutane. Additionally, 1,2-dimethylcyclobutane can also be considered. In terms of stereoisomers for these cyclic structures, only 1,2-dimethylcyclobutane has stereoisomers due to the presence of chiral centers, while the others do not.
The dehydration of cyclohexanol can form two isomers: cyclohexene and cyclohexadiene. These isomers result from different locations of the double bond formed during the dehydration process.
The two isomers of (CH₃)₂NOH, known as dimethylhydroxylamine, are the syn and anti isomers. In the syn isomer, the hydroxyl (–OH) group and the nitrogen atom are on the same side of the molecule, while in the anti isomer, they are on opposite sides. These isomers differ in their spatial arrangement around the nitrogen atom, resulting in distinct properties.
Nonane has a total of 75 isomers, which includes straight chain isomers, branched chain isomers, and cyclic isomers.
There are two isomers for dibromopropane: 1,2-dibromopropane and 2,2-dibromopropane.
C3H4O can have two isomers: propynal and cyclopropanone.
Tartaric acid has three stereoisomers: meso-tartaric acid and the two enantiomers, D-tartaric acid and L-tartaric acid.
Two sugar isomers have the same chemical formula but different structural arrangements.
If they're isomers, they by definition have the same molecular formula.
Butune is a nonsubstituted alkane that can exist as one of only two isomers.
There are three cyclic isomers possible for the formula C3H6O: two variations of oxirane and one of cyclopropanol. There are two acyclic isomers: propanal and 2-propanol.
C3H12 can have two different isomers: n-propane, which is a straight chain molecule, and isobutane, which is a branched molecule.
There are two types of geometric isomers possible in octahedral complex ions: cis and trans isomers. For a complex with six different ligands, there can be a maximum of 30 different cis and trans isomers.
Two: 1,1-dichloroethane and 1,2-dichloroethane.
The dehydration of cyclohexanol can form two isomers: cyclohexene and cyclohexadiene. These isomers result from different locations of the double bond formed during the dehydration process.
Isomers have the same chemical formulas, but different structures. They can be drastically different in structure, such as constitutional isomers, which differ in the way that certain groups are linked to a carbon back bone. They can be very subtly different as well, such as stereo isomers, which are almost completely same except for their biological activities and interactions with plane polarized light.
