They are both C4H10 but isobutane has another structure, called Isomer

Butane: Isobutane: H H H H H H H H-C-C-C-C-H H-C-C-C-H H H H H HHCHH H

Isobutane comes in Y shape not in series as n-butane.

In refineries, they transform n-butane to iso-buatene. So, they can use it in alkaline units to produce gasoline

The molecules have different structures, that is, they atoms in the two compounds are bonded in a different arrangement, even though the atoms themselves are the same.

A molecule of butane is a molecule with four carbon atoms in a chain. The two carbon at the end of the chain are bonded to three hydrogen atoms and those in the middle are each bonded to two.

A molecule of isobutane consists of a central carbon atom bonded to a single hydrogen atom and three carbon atoms. Each of those three carbon atoms is additionally bonded to three hydrogen atoms.

basically there is no difference between the two isomers of butane .actually isomers are similar compounds with different possible skeletal structures ;for example ,butane is a hydrocarbon with 4 carbon atoms ,so its possible isomers are- n-butane and iso-butane.

They have the same molecular formula but differ in their structural formula. As in, they are both C4H10, but they are shaped differently.

Butane:

. H H H H

... | | | |

H-C-C-C-C-H

....| | | |

.. H H H H

Isobutane:

. H H H

.. | | |

H-C-C-C-H

..... |

. H-C-H

.... |

.... H

Note: Isobutane is slightly slanted. Also, ignore the dots, their just so i can show the bonds correctly

The usual way of writing this formula without more flexible typographic resources than this format provides is CH3CH(CH3)CH3.
