Question

What is metamerism?

Answer 1

Isomers in chemistry are molecules or polyatomic ions that have the same molecular formula — that is, the same number of atoms of each element — but different atomic configurations in space. Isomerism refers to the existence or potential of isomers. Isomers don't always have the same chemical or physical characteristics as one another. Structural or constitutional isomerism, in which the bonds between the atoms differ, and stereoisomerism or spatial isomerism, in which the bonds are the same but the relative locations of the atoms differ, are the two primary types of isomerism.

Complete answer:
The existence of distinct alkyl chains on each side of the functional group causes this form of isomerism. It's a rare form of isomerism that only occurs in compounds with a divalent element (like sulphur or oxygen) surrounded by alkyl groups. Metamers are molecules with the same chemical formula but distinct atom or group positions on each side of bridging functional groups. The existence of distinct alkyl chains on each side of the functional group causes this form of isomerism. It's a rare form of isomerism that only occurs in compounds with a divalent element (like sulphur or oxygen) surrounded by alkyl groups. Metamers are compounds with the same chemical formula but variable numbers of carbon atoms (alkyl groups) on each side of a functional group (e.g., O, S, NH, C(=O), esters, amides, etc.) in organic chemistry.
Metamers include, for example, diethyl ether and methyl propyl ether.

Note:
Stereoisomers contain the same atoms or isotopes linked by the same sort of bond, but they differ in their forms, which are the relative locations of those atoms in space, excluding rotations and translations. In theory, every atomic arrangement in a molecule or ion may be progressively changed to any other arrangement in an unlimited number of ways by moving each atom along an appropriate path. Changes in atom locations, on the other hand, will typically affect a molecule's internal energy, which is controlled by the angles between bonds in each atom as well as the distances between atoms (whether they are bonded or not).
