Question

I need help with part C, Can someone please explain why the CF3 group does that? does it stabilize the carbocation???

Tosylic acid and the optically active alcohol (Right) react, and product A is the major product. The stereochemistry of this product is intentionally left out- see part 2B.) HOTS HO (optically active) Product A A Propose a mechanism for the formation of Product A. Show correct arrows, relevant lone pairs, bonds, and formal charges. B) How many stereoisomers are in Product A? raw each one that is present in the final mixture making sure they have the right configurations. And state their relationship C) When a related substrate is used, acyclic products B and C are observed instead. Explain why this occurs OH OH CF CF HOTS HO HO optically active) Product B Product C

Explanation / Answer

Solution:

CF3 in the molecule stabilises the carbocation and due to the presence of halo atom favours the formation of superimposable mirror image hence two form of product B and C are formed in stabilized condition.
