* Isomers are molecules that have the same molecular formula but different structural arrangements of atoms.
* Molecular Formula represents the total number of atoms of each element in a molecule.
In this case, the molecular formulas C4H10 and C4H10O are different. The second formula includes an oxygen atom that the first one lacks. Therefore, these molecules have different compositions and cannot be isomers.
Here's a further explanation:
* C4H10 represents hydrocarbons called butanes. There are two isomers of butane: n-butane (straight chain) and isobutane (branched chain).
* C4H10O represents a variety of compounds, including alcohols (like butanol), ethers (like diethyl ether), and others. These compounds have different functional groups (like the -OH group in alcohols) and different structural arrangements than butanes.
In short, to be isomers, molecules must have the same molecular formula, but different structural arrangements. C4H10 and C4H10O have different molecular formulas, so they cannot be isomers.
