Question

Ring chain isomerism is due to:

• A. The difference in the position of the substituent atom or group or an unsaturated linkage in the same chain.
• B. The difference in the nature of the carban chain - straight or branched, which forms the nuclear of the molecule
• C. Difference in the nature of the functional groups present is the isomers.
• D. Difference in the mode of linkage of carbon atoms and the isomers may have open or closed structure.

Answer 1

The correct option is D

Difference in the mode of linkage of carbon atoms and the isomers may have open or closed structure.

Ring­chain isomerism is the phenomenon shown by compounds having same molecular formula but possessing open chain and closed chain structures. The compounds showing this type of isomerism are known as ring chain isomes.D is the very definition of ring - chain isomerism.
