Q.What is metamerism? Give the structure and IUPAC name of the metamers of 2-methoxypropane.

Step 1. Metamerism is a type of isomerism shown by compounds belonging to the SAME homologous/functional series (here, ethers) that share the same molecular formula but differ in the SIZE of the alkyl (or aryl) groups distributed on either side of the same functional group.

Step 2. 2-Methoxypropane, CH3-O-CH(CH3)-CH3, has molecular formula C4H10O, splitting its four carbons as 1 (methyl) + 3 (isopropyl) across the ether oxygen.

Step 3. A metamer with the SAME formula but a DIFFERENT alkyl-group split is ethoxyethane (diethyl ether), CH3-CH2-O-CH2-CH3 -- a 2-carbon + 2-carbon split. …

Define metamerism precisely (same formula, same functional class, different flanking-group split), then enumerate the other C …

• Confusing metamerism with simple chain isomerism -- metamerism specifically concerns how the SAME functional group's two flanking g …
