How many isomers can be obtained from C4H10?

C_4H10 is the molecular formula for butane, which is an alkane with four carbon atoms. Isomers are molecules with the same molecular formula but different structural arrangements of their atoms. In the case of butane, there are two main types of isomers: constitutional isomers and stereoisomers. Constitutional isomers have the same molecular formula but different connectivity between atoms. For example, butane has two possible constitutional isomers: n-butane, where the four carbon atoms are arranged in a straight chain, and isobutane, where the carbon atoms form a branched chain. Stereoisomers have the same molecular formula and connectivity between atoms, but differ in the spatial arrangement of their atoms. Butane has no stereoisomers because all of its atoms are connected by single bonds, which do not allow for different spatial arrangements. Therefore, the number of isomers that can be obtained from C_4H10 is 2, which correspond to its two constitutional isomers.
