which of the compounds is a cycloalkene?\nch2 = ch - ch = ch2\nch3 - ch = ch2

which of the compounds is a cycloalkene?\nch2 = ch - ch = ch2\nch3 - ch = ch2
Answer
Brief Explanations:
A cycloalkene is a cyclic hydrocarbon with a carbon - carbon double bond. The first option is a cyclobutene (a 4 - membered cyclic ring with a double bond), which fits the definition. The second option is a linear di - ene. The third option is benzene, an aromatic compound. The fourth option is a linear alkene. The fifth option is a cycloalkane (no double bond).
Answer:
The first option (the square - shaped structure representing cyclobutene)
