Question 21 In the standard electrophilic addition of a hydrohalide (H-X) to an alkene, what can be said about the stereochemistry of the product? O The stereochemistry will be anti, since the sigma bond will rotate once the pi bond is broken O The stereochemistry will be syn, since the nucleophile will be generated on the same side of the alkene as the electrophile. O The stereochemistry will be random, since the carbocation generated is planar and attack can come from either side. O None of these, because it is not possible to generate a chiral center with stereochemistry through an electrophilic addition reaction A Moving to another question will save this response. 080 acer5) Draw two reasonable resonance structures and the hybrid of the intermediate formed in the following reaction.
