2-Methylhexane (C 7 H 16, also known as isoheptane, ethylisobutylmethane) is an isomer of heptane. It is structurally a hexane molecule with a methyl group attached to its second carbon atom.
2-Methylpentane, trivially known as isohexane, is a branched-chain alkane with the molecular formula C 6 H 14.It is a structural isomer of hexane composed of a methyl group bonded to the second carbon atom in a pentane chain.
For example, cyclobutane and methylcyclopropane are isomers of each other (C 4 H 8), but are not isomers of butane (C 4 H 10). Branched alkanes are more thermodynamically stable than their linear (or less branched) isomers. For example, the highly branched 2,2,3,3-tetramethylbutane is about 1.9 kcal/mol more stable than its linear isomer, n ...

In one isomer the CO ligands are terminal. When a pair of CO are bridging, cis and trans isomers are possible depending on the location of the C 5 H 5 groups. An example of an organometallic isomerization is the production of decaphenylferrocene, [(η 5-C 5 Ph 5) 2 Fe] from its linkage isomer. [8] [9] Formation of decaphenylferrocene from its ...
The isomers which have been cited as examples of metamers in chemical literature consist primarily of ethers; [3] but this could by the same reasoning be extended to thioethers, secondary as well as tertiary amines, esters, secondary as well as tertiary amides, (mixed) acid anhydrides etc. Metamers in organic chemistry

For the same reason, "ethoxymethane" is the same molecule as methoxyethane, not another isomer. 1-Propanol and 2-propanol are examples of positional isomers, which differ by the position at which certain features, such as double bonds or functional groups, occur on a "parent" molecule (propane, in that case).
