Alkenes can be converted to alcohols by hydroboration-oxidation. (a) Draw the structure of the alcohol or alcohols formed in the reaction sequence. Clearly indicate stereochemistry by drawing a wedged bond, a dashed bond and two O Hint in-plane bonds per each chiral carbon. Draw hydrogen atoms that are connected to wedge-and-dash bonds.(b) Characterize the product or products of the reactions. The first step of the reaction, hydroboration, involves addition of BH, to the double bond, with -BH, attached to one carbon and hydrogen Be sure to draw hydrogens on oxygen, where applicable. attached to the other.
