Organic chemistry student Peter is tasked with synthesizing (R)-3-ethylpentan-2-ol. Using his knowledge of alkene reactions, he runs a hydroboration/oxidation reaction on 3-ethylpent-2-ene. Upon isolation, Peter runs an optical rotation experiment to determine the enantiopurity of his alcohol. Which of the following statements would be MOST correct regarding the optical rotation of his synthetic sample (Note: the specific 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°
