Materials:
15 cm testtubes, stopper, 1-L beaker, 2-methyl-2-propanol, gas delivery system, hot plate, using a rubber stopper, two side inverted gas tube, and a clamp. Water, 2-methyl-2-propanol, 0.1 M aqueous potassium permanganate, bromine, sulfuric acid, and dichloromethane.

Fill 4 15 cm test tubes with water, stopper them tightly and invert them into a 1-L beaker that is about filled with water. Measure out 1 mL of 2-methyl-2-propanol into a test tube, and add 5 drops of concentrated sulfuric acid, swirl, mix, and drop in a few boiling chips. Construct a gas generator with the reaction tube clamped to a ring stand and the free end of the gas delivery tube under water. Move one waterfilled test tube so that its mouth over is the outlet of the gas delivery tube. Heat the reaction vessel gently with a hot water bath until a steady stream of gas bubbles emerges from the delivery tube and fills the test tube. As they are filled, remove and stopper the test tubes. Repeat until all of the test tubes are filled. Remove the gas delivery system from the water, and then remove the heat source and cool in cold water to stop the generation of gases. Discard the gas in the first test tube. Add 5 drops of 0.1 M aqueous potassium permanganate to the second tube, stopper, and then shake it. Add 5 drops of 1 M bromine in dichloromethane to the third tube, stopper, and shake it. Light one end of a wood splint with a match or a burner flame, and lower the burning end into the fourth tube.

Conclusion: After completing the experiment, I was able to complete the reaction. In the end, the products that formed were water and isobutylene, which is an alkane. This is also the reason why the last test tube ignited, because isobutylene is similar to butane, which is used to spark lighters.
