Organic chemistry student Peter is tasked with synthesizing (R)-3-ethylpentan-2-ol.Using his knowledge of alkene reactions, he runs a hydroboration/oxidation reactionon 3-ethylpent-2-ene. Upon isolation, Peter runs an optical rotation experiment todetermine the enantiopurity of his alcohol. Which of the following statements wouldbe MOST correct regarding the optical rotation of his synthetic sample (Note: thespecific rotation of (S)-3-ethylpentan-2-ol is +28.2°).O [x] of the sample will be +28.2°O [x] of the sample will be 0°O [x] of the sample will be between 0° and -28.2°O [a] of the sample will be -28.2°O [x] of the sample will be between 0° and +28.2°

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?
