The following test results were obtained for an unknown: Which of the following is the best choice for the identity of the unknown? 2-Methylheptane Cycloheptene Toluene Explain your answer: ______________ An unknown has a normal boiling point of 133 degreeC. Which of the following tests would be most useful in deciding whether the unknown is ethylcyclohexane or ethylbenzene? Bromine test KMnO4 test Neither test Either test Explain your answer: _____________ An unknown has a normal boiling point of 67 degreeC. Which of the following tests would be most useful in deciding whether the unknown is hexane or 1-hexene? Bromine test KMnO4 test Neither test Either test Explain your answer: ________________________________

Explanation / Answer

2) answer is 2-methylheptane, becuase KMnO4 reacts with alkenes (cycloheptane) and aromatic srings like toluene, besides the reperted boiling point of 2-methylheptane is 116C (close to 117)

3)either test becuase 1-hexene reacts with bromine and also with KMnO4 but hexane DO NOT react with those reagents

4)

either test becuase ethylbenzene reacts with bromine and also with KMnO4 but ethylcyclohexane DO NOT react with those reagents
