Question

Which of the following compounds are metamers?

• A.

  

• B.

  

• C.

  

• D.

  

Answer 1

The correct option is A

The explanation for the correct option:

Option (A):

• Metamers are the isomers with the same molecular formula but different alkyl groups around the same functional group.
• It is a type of functional isomerism.

• These two compounds have the same functional group but have a different arrangement of alkyl groups around the functional group.
• Hence, these are metamers.

The explanation for the incorrect options:

Option (B)

• These two compounds have different functional groups.
• The first compound has an alcohol group and the second compound has an ether group as a functional group.
• Hence, these can not be metamers.

Option (C)

• It exhibits chain isomerism as the same number of carbon atoms are arranged in different chain arrangements.
• Hence, they are not metamers.

Option (D)

• These two compounds have different functional groups.
• The first compound has a ketone group and the second one has an aldehyde group as a functional group.
• Hence, these cannot be metamers.

Hence, option (A) is the correct option.
