The Correct Option is B
Solution and Explanation
Step 1: Understanding degree of unsaturation.
For \(C_4H_6\), degree of unsaturation is: \[ DU = \frac{2C + 2 - H}{2} = \frac{8 + 2 - 6}{2} = 2 \]
Step 2: Given condition interpretation.
One unsaturation is due to a ring and one due to a double bond in the ring.
Step 3: Possible cyclic structures.
Possible cyclic isomers include: - Cyclobutene - Methylcyclopropene (different positional arrangements) Thus total distinct cyclic isomers = 3.
Step 4: Eliminating duplicates.
Structures are counted based on constitutional differences only. Stereoisomers are not considered here.
Step 5: Final conclusion.
Hence total cyclic isomers = 3.
Final Answer: \[ \boxed{3} \]
