Hey guys if anyone has the book you can reference my question on Page 16, problem 137 in the EK Organic 1001. Question: IN the assignment of absolute configuration, what priority does the CHO group have in the structure? Okay so the chiral carbon is connected to a Br, OH, "CHO", and CH3. Now the answer key says that the CHO takes second priority? Isn't that false? The priority should be 1.Br, 2. OH, 3."CHO" and 4. CH3 right. Priority begins with highest MW first and if there is a tie you look for the next substituent. Or maybe I am wrong about this one? What do you guys think?
