all 4 please!! will thumbs up

6. Complete this multi-step reaction sequence on paper: Convert 2-pentanol into 2,3-dibromopentane. Draw structures of the starting material (2-pentanol) and final product (2,3-dibromopentane), and show the two reactions needed for this synthesis. Include the structure of the intermediate compound, and the reagents and conditions for each reaction. Then explain why 1,2-dibromopentane would not be a significant product of this synthesis. 2. Using structures, write the chemical reaction for the dehydration of cyclohexanol to produce cyclohexene. Indicate any important reagents and reaction conditions (temperature, use of catalyst). 3. Describe the TwO methods you'll use to confirm that you successfully dehydrated cyclohexanol to make cyclohexene. 4. Your lab instructor directs you to use 12.5 grams of the cyclohexanol to start the synthesis. If the density of cyclohexanol is 0.9624grams/cm3, what volume of cyclohexanol should you measure out in your 25mL graduated cylinder? Show the colculation completely, giving close attention to the use of units and significant figures
