C4H10 can refer to two different compounds, both with the same molecular formula but different structures:

* Butane: This is the straight-chain alkane with the formula C4H10. It is a colorless, flammable gas commonly used as a fuel.

* Isobutane: This is the branched-chain isomer of butane. It has the same molecular formula but a different arrangement of atoms. It is also a colorless, flammable gas.

So, the compound name of C4H10 depends on the specific structure: butane for the straight-chain version and isobutane for the branched-chain version.
