When ethylbenzene is treated with NBS and irradiated with UV light, two stereoisomeric compounds are obtained in equal amounts. Draw the products and explain why they are obtained in equal amounts: NBS two products hv X Incorrect. Modify the given structures to draw the two stereoisomeric products. H,C L CH, -Br Br Edit Drawing eTextbook and Media Your answer is correct. Of the following, which does NOT explain why the products are obtained in equal amounts? A racemic mixture is formed. O The reaction generates a new chiral center. O Backside attack on the radical intermediate leads to two diastereomers. O Attack on either face of planar radical intermediate is equally likely.
