Ethane has no structural isomers and hence there is no n-ethane and iso-ethane.
Butane C4H10 exists in two isomeric forms ,n-butane and Iso-butane
It is either n-butane or methyl propane (i.e. 'iso-butane' )
Isomerism. The structures of the molecules are different even when the numbers of atoms are the same. Organic molecules are the most common examples of this. Compare n-butane and iso-butane same formula different structures. See link
Butane is homogeneous. Butane may mean n-butane, iso-butane or a mixture of the two isomers. If the sample were a mixture of the two isomers then it would be a homgeneous mixture.
Methane, ethane and propane don't have isomers (confirmers are possible) , butanes are two n-butane and iso-butane, pentanes are three n-pentane, iso-pentane and neo-pentane.
iso propane and iso butane
The name butane is applied by IUPAC to the unbranched form of B4H10.However many chemists use the name butane to refer to both isomers ofB4H10 , n-butane the unbranched form and iso-butane the branched form.
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.
Two isomers with the formula C4H10 are: n-butane: CH3-CH2-CH2-CH3 iso-butane: (CH3)2-CH-CH3
There are two structural isomers approved by IUPAC (International Union of Pure and Applied Chemistry) 1.) n-butane (normal butane) is a straight chain 2.) iso-butane (or methyl-propane) is a chain of three with one carbon attached to the middle of the chain
Structural isomers have same molecular formula but different structural formula. Structural isomers for Butane having formula C4H10 are two. One is n-butane and the other is iso-butane.
our regular household gas is called LPG. it contain butane, propane, iso-butane.
The difference could be in the proportions of the elements or in the structure of the compoundsThere are three iron oxides where the proportions of the elements are different, FeO, Fe2O3, Fe3O4There are two isomers of butane C4H10 , two structural forms, n-butane and iso-butane.
n-butane : Melting point −138.4 °C (135.4 K), boiling at −0.5 °C (272.6 K)iso-butane (methylpropane): Melting point -159.6 °C, (114 K) , boiling at -11.7 °C, (261 K)

n-butane formula is: C4H10.
structural isomer explain the change in the arrangement of atoms around carbon atom even normal or iso-structure. But the functional isomer show the change in the functional group of compounds
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
By reverse isomerisation process. Process is patented by UOP.
Functional isomerism , categorized under structural isomerism
dot formula of n-butane
There are two: n-butane & 2-methylpropane.
Geometric isomerism also known as cis-trans isomerism or E-Z isomerism
Butane C4H10 has 2 isomersbutane C-C-C-C (n-butane)2-methyl propane CH3)2-CH-CH3 (isobutane)
