(b) acetamide (c) phenol (d) benzene
Answers
Answer:
Cyclohexene is a hydrocarbon with the formula C₆H₁₀. This cycloalkene is a colorless liquid with a sharp smell. It is an intermediate in various industrial processes. Cyclohexene is not very stable upon long term storage with exposure to light and air because it forms peroxides.
