Hexane and 2-methylpentane
Both of these compounds are alkanes with four carbon atoms and both of these compounds have the molecular formula C4H10. These are structural isomers of each other.
Structural isomers also called constitutional isomers are different compounds that have same molecular formula but different molecular structure. Structural isomers have same number of each type of atoms but the atoms are connected in a different order in them. Structural isomerism is seen in organic compounds. It can be due to different arrangement of carbon chain, due to different position of functional group on the carbon chain, due to different functional groups that give their family of compounds same molecular formula. Difference in arrangement of atoms is visible if structural formulas are written for compounds having same molecular formula. Like structural isomers, stereoisomers also have same molecular formula. Stereoisomers are not structural isomers. Stereoisomers have their atoms connected in same sequence( same constitution), but they differ in the arrangement of atoms in space. Cis and trans isomers of alkenes are examples of stereoisomers. Carbon chain arrangement, position of functional groups, and everything that could be different in structural isomerism is same here.
For two compounds to be isomers, they must be composed of exactly the same atoms (that is to say, equal numbers of each element in their formula) but the atoms are arranged differently.
are cyclohenane and n-hexane isomers of each other?explain
Indicate whether each of the following pairs represent constitutional isomers, the same compound, or different compounds 2-methoxybutane and 3-methyl-2-butanol

Structural Isomers- differ in the covalent arrangement of their atoms Geometric Isomers- differ in spatial arrangement around double bonds Enantiomers- mirror images of each other
For two compounds to be isomers, they must be composed of exactly the same atoms (that is to say, equal numbers of each element in their formula) but the atoms are arranged differently.
Just try to draw the structures with different arrangements of carbon atoms having four valencies each, there are 5 isomers for this formula.
are cyclohenane and n-hexane isomers of each other?explain
Yes. Propyl alcohol has 2 forms, normal n-propyl alcohol and isopropyl alcohol. They have different boiling points, different freezing points. They are 2 different compounds. The change in structure causes properties to be different, thus different compounds.

no they are not. they are stereoisomers(configurational) Structural isomers. isomers that differ in the arrangement literally. so the difference between the cylic glucose molecule that is a ring and the non ring glucose. these two are structural isomers. if molecule A and B have the same molecular formula but look different and are thus arranged differently they are structural isomers. conformational isomers. these are isomers that differ from each other simply by the rotation around a single bond. if molecule B can be twisted around the single bonds to get molecule A then A and B are conformational isomers. configurational isomers (stereoisomers). if molecules A and B do not fall into the above two categories, then they are stereoisomers. these type of isomers differ in the spatial arrangement of atoms. so if molecule A was the mirror image of molecule B then these two molecules would be a type of stereoisomers called (Enantiomers). for alpha glucose the OH group attached to the anomeric carbon is not the same as teh CH2OH group on the other side of the hemiacetal( on the other side of the ether oxygen.). ie. if the OH is axial down then the CH2OH is equatorial up. and vice versa. the molecule is beta glucose when these two substituents are the same in this aspect. both either equatorial or axial. the difference between axial and equatorial is spatial adn in the arrangement of atoms connected to the carbon ring and solely a difference in this aspect (alpha or beta) means the molecules are stereoisomers.
Yes, the o-, m-, and p-cresol molecules are structural isomers of one another, each having a benzene ring and -OH group on C1 and methyl group either in the o-, m-, or p- position.
In Chemistry, an enantiomer are mirror images of each other. An optically active isometer has equal parts for the enantiometer. An isomer are compounds that are structured differently but have the same molecular formula.
