Question

If different class of compounds are present it is termed as:

• A. chain isomerism
• B. position isomerism
• C. ring chain isomerism
• D. metamerism

Answer 1

Answer: (C)

ring chain isomerism

Compounds with same molecular formula but two different structures as cyclic and open-chain are called ring chain isomers of each other. In ring chain isomerism class of the compound are different. On is cyclic a close chain compound where as other is a open chain compound.
