Just want to make sure i am drawing the corret starting material before i submit. In this lab exercise would it be the hex-1-ene?

Synthesis of Alcohols by Hydrating an Alkene
Refer to Lesson 35 for background information and the procedure to complete the prelab on Mastering Chemistry
Procedure
Part A. Synthesis of Hexan-2-ol.
This part of the experiment must be done in the hood.
1. Make an ice bath in a 250 mL beaker.
2. Cool 15 mL of distilled water in a boiling tube provided by your instructor.
3. Measure out 5 mL of hex-1-ene using a measuring a 10-mL graduated cylinder and pour it into another boiling
tube. Cover the mouth of the tube with a wool.
4.
Cool the hex-1-ene in the ice bath for about three minutes.
5. Measure out 5 mL of 75% sulfuric acid into another measuring cylinder.
6.
Remove the wool from the Boling tube. Slowly add the acid to the hex-1-ene, keeping the tube in the ice bath
and stirring the mixture with a glass rod. ADDING LARGE AMOUNTS OF THE ACID MAY CAUSE EXPLOSION!
7. When all the acid has been added, continue to stir the mixture until ONLY ONE LAYER IS OBSERVED. This will
take about 5-10 minutes. Cover the boiling tube with the wool.
8.
Allow the mixture to stand in the ice bath for another 5 minutes, then carefully add an equal volume of cold
distilled water from the other boiling tube. The mixture should separate into two layers. The top layer contains
the product, the lower layer contains mainly sulfuric acid solution.
Part B. Separation and Washing the Product
1. Transfer the contents of the boiling tube from step 8 into a 50-mL beaker, and then pour the reaction mixture
into a small separating funnel, stopper, shake and allow the contents to settle.
2. Open the stopcock to run off the lower layer into another 50-ml beaker.
3. Wash the product by adding 10 mL distilled water to the separating funnel, stopper and shake. Remove the
lower layer.
4.
Place 25 g of anhydrous sodium carbonate in a 50-mL or 100-mL Erlenmeyer flask.
5. Run off the product of the separating funnel into the Erlenmeyer flask. Swirl the flask frequently for twenty
minutes to dry the product.
Part C. Distillation of the product
1. Set up a simple distillation apparatus.
2. Decant as much as possible the product from the Erlenmeyer flask into the distilling flask (25-mL or 50-mL round
