Designing a Synthesis

Organic synthesis is a branch of chemical synthesis that involves the planned construction of organic compounds/molecules from smaller units that possess functional groups. Friedrich Wöhler was the first scientist who designed the synthesis of an organic compound, urea from inorganic starting materials silver cyanate with ammonium chloride via a simple, one-step synthesis.

I am completing my lab assignment called synthesis of an alcohol by hydrating an alkene. Get two small test tubes. Place 1 mL of bromine water into each of the two test tubes.Add about three drops of the product and hex-1-eneinto each of the two test tubes. Swirl the contents of the tubes. Record you observations. My observations were: cyclohexene turned clear, the cyclohexanol turned yellow. Based on these reults, was I able to synthesize the of hexan-2-ol from the hydration of hex-1-ene?
