Title: Checking major products of electrophilic addition reactions with stereochemistry
Post by: amimi on November 08, 2025, 05:05:59 PM
Hello! I was wondering if you could check these problems. Thank you so much!IMG_60A853660757-1_Page_2.png

All products are correct for regiochemistry.You have used Marks and antimarks correcetly.However you are doing error in identification of racemeic mixture.
In hydroiodination (HI) you are not getting any chiral centre.Check Carbon with methy and iodine is connected to same groups in the ring.Similarly in oxymercuration and demercuration , acid catalyzed hydration and reduction of pi bond with H2 in the presenece of metal catalyst.

Thank you! So for those four structures I incorrectly said were racemic, I would circle no instead and place everything on lines instead of wedges or dashes?
