Question

Ethers show the phenomenon of:
A.Position isomerism
B.Functional group isomerism
C.Metamerism
D.Cis-trans isomerism
​

Answer 1

Option - D is correct.

Ethers exhibit chain isomerism ,functional isomerism, Metamerism and Chain isomerism.Ethers with the same formula and having different carbon chain skeletons are called chain isomers.

Functional isomers : Ethers are isomeric with alcohols.

Metamerism Isomers with the same molecular formula but different alkyl groups (around the functional group) are called metamers. An ether with formula C4H10O has 3 metamers.

Hence option D is correct.

Answer 2

Ethers show the phenomenon of: C.Metamerism

Ethers:

• Ethers are a type of chemical compound in which the oxygen atom is joined to two alkyl or aryl groups to form an ether group.
• The Latin word "aether," which meaning "to ignite," is the source of the English term "ether."
• Ethers typically ignite when exposed to high pressure and at room temperature.
• The ethoxyethane (diethyl ether), methoxy ethane (methyl ethyl ether), 2-methoxy-2-methylpropane (MTBE), and phenoxy benzene examples mentioned above are just a few (diphenyl ether).

Metamerism:

• The term "metamerism" refers to isomerism in which molecules with the same molecular formula but distinct alkyl groups on each side of functional groups are considered to be the same chemical.
• Metamers of each other are substances with the same chemical formula but a different number of carbon atoms surrounding the functional group. This phenomenon is referred to as metamerism.
