According to metamerism in polyvalent functional groups, if both alkyl groups' around functional group are different then they are considered as metamers but in few books it is given that if one of the alkyl group is different then it is a metamer. In my opinion, for e.g. diethyl ether and methyl propyl ether are metamers.Meaning of Metamerism: Metameric segmentation or metamerism is an architectural body plan in some animals in which the similar body segments and organ systems are serially repeated one after another. The similar body segments are called metameres or somites. The animals which exhibit such features called metamerically segmented.Metamerism (biology) explained. In biology, metamerism is the phenomenon of having a linear series of body segments fundamentally similar in structure, though not all such structures are entirely alike in any single life form because some of them perform special functions. In animals, metameric segments are referred to as somites or metameres.
Metamerism is the effect where a color that appears the same shade to a second color under certain conditions, e.g., in daylight, may look totally different under different conditions, e.g., when viewed in artificial light such as garage or street lighting.Metamerism index is a single-number index which indicates how well two materials that match under one illuminant will match under another illuminant. Typically, CIE Illuminant D65 is the reference illuminant and the test illuminant is one chosen depending on the end use of the material. For example.
Metamerism - definition The phenomenon in which different alkyl chain on either side of the functional group present in the molecule is called as metamerism. Example: Methoxypropane and Ethoxyethane.
